The Path's Guidance for Success sections can include the following two elements:
Images and Links: Images and links can be used to provide visual cues and additional resources for the sales representatives. For example, an image of a checklist or a link to a best practice document can help the reps complete the required tasks at each stage. Images and links can be added using the rich text editor in the Path Settings page.
Rich Text: Rich text can be used to provide text-based guidance, such as tips, reminders, instructions, or motivational messages. For example, a rich text guidance can tell the reps what information they need to gather from the customer or what actions they need to take to move the opportunity forward. Rich text can be formatted using the rich text editor in the Path Settings page.Reference:

The two elements that can be used in the Path's Guidance for Success section are Images and Links and Rich Text. Images and Links can be used to provide visual elements to the Guidance for Success section, while Rich Text can be used to provide text-based explanations and instructions. In addition, a Progress Indicator can be used to show the user's progress through the Path.
Images and Links can be used to provide visual elements to the Guidance for Success section. For example, if the user needs to read an article, a link to the article can be included, as well as an image of the article cover. Similarly, if the user needs to view a video, a link to the video and an image of the video can be included.
Rich Text can be used to provide text-based explanations and instructions. This can include explanations of what the user should be doing at each stage of the Path, as well as any other helpful information.
Finally, a Progress Indicator can be used to show the user's progress through the Path. This can help the user understand where they are in the Path and how far they have left to go.

Dynamic Forms is a feature that allows users to customize the form fields and sections displayed to users on a page layout. Dynamic Forms can be used to create user-centric, intuitive, and dynamic record creation screens for custom objects, such as Appointment.When creating a record using Dynamic Forms, the UX designer should consider the following two aspects12:
The use of tabs when creating the record is not allowed. Dynamic Forms does not support the use of tabs within the form, as tabs are not compatible with the record creation process. Tabs are only available for viewing or editing existing records, not for creating new ones. Therefore, the UX designer cannot use tabs to separate the fields for different record types or software options on the record creation screen.
Fields can be organized into sections. Dynamic Forms allows the UX designer to group fields into sections, and place them anywhere on the page layout. Sections can have labels, collapsible headers, and visibility rules. The UX designer can use sections to create a logical and clear structure for the form, and to show or hide fields based on user input, data, or profile. For example, the UX designer can create a section for each software option, and use visibility rules to display only the relevant section based on the user's selection.
The following two aspects are not true when creating a record using Dynamic Forms, and should be disregarded:
The form will not be available on mobile devices. Dynamic Forms is compatible with mobile devices, and the UX designer can preview and test the form on different device sizes and orientations.The form will automatically adjust to the screen size and layout of the mobile device, and provide a responsive and consistent user experience3.
All software option sections of the form will always be visible. Dynamic Forms allows the UX designer to use visibility rules to control the visibility of fields and sections on the form. Visibility rules can be based on user input, data, or profile. The UX designer can use visibility rules to show or hide software option sections based on the user's selection of the record type or the software option.This can reduce the clutter and complexity of the form, and provide a personalized and flexible user experience4.Get Started with Dynamic Forms Unit | Salesforce Trailhead,Salesforce Dynamic Forms: Overview & Deep Dive Tutorial,Dynamic Forms and Actions FAQ | Salesforce Help,Create Dynamic Forms with Visibility Rules | Salesforce Trailhead

A sales rep who owns an opportunity record will have read-only access to the related account record, if the organization-wide default for the Account object is private. This is because the opportunity owner is automatically granted read-only access to the account that the opportunity is associated with, regardless of who owns the account. This is called implicit sharing, and it is a built-in feature of Salesforce to ensure that users can access the data they need to do their work. However, the opportunity owner will not be able to create, edit, or delete the account record, unless they have other sharing mechanisms that grant them higher access, such as role hierarchy, sharing rules, manual sharing, or View All or Modify All permissions.Reference:

Two best practices that should be considered when using a custom Lightning component to fulfill a specific business requirement are:
Find the closest Salesforce Lightning Design System (SLDS) Blueprint to help inform the custom Lightning component. The SLDS is a collection of design guidelines, UI components, and code samples that help you create consistent and beautiful user interfaces for Lightning applications. The SLDS Blueprints are examples of common UI patterns and components that are built with the SLDS and follow the design principles and best practices. The Blueprints can help you inform the custom Lightning component by providing inspiration, guidance, and code snippets that you can modify and reuse. The Blueprints can also help you ensure that the custom Lightning component is compatible and consistent with the rest of the Lightning application and the Salesforce platform. [UX Designer Certification Prep: Salesforce Design System],Lightning Design System Website Exhaust the list of available base Lightning components in the Component Library. The base Lightning components are a set of pre-built UI components that you can use to create custom Lightning components. The base Lightning components are built with the SLDS and provide the functionality and interactivity that you need for common UI elements, such as buttons, icons, forms, tables, charts, and more. The base Lightning components also handle the accessibility, security, and performance aspects for you, so you don't have to worry about them. The Component Library is a reference guide that provides documentation and examples for the base Lightning components, as well as other Lightning web components and Aura components. The Component Library can help you explore the list of available base Lightning components and see how they work and how to use them. The Component Library can also help you avoid reinventing the wheel and save time and effort by using the base Lightning components as much as possible, and only creating custom Lightning components when there is no suitable base Lightning component for your requirement. [UX Designer Certification Prep: User Testing and Evaluation],Developer Center's Lightning Component Library Prioritizing Aura markup even if there is a Lightning Web Component (LWC) available, and creating HTML markup and linking the SLDS stylesheet via static resource are not best practices that should be considered when using a custom Lightning component to fulfill a specific business requirement. These practices can lead to suboptimal performance, maintainability, and compatibility issues for the custom Lightning component. Aura markup is the older syntax for creating Aura components, which are the predecessor of Lightning web components. Lightning web components are the newer and faster way of creating custom UI components for Lightning applications, using modern web standards and best practices. Lightning web components also have better interoperability and compatibility with Aura components and other web components, as well as with the base Lightning components and the SLDS. Therefore, it is recommended to use Lightning web components over Aura components whenever possible, and to use LWC markup instead of Aura markup for creating custom Lightning components. [UX Designer Certification Prep: User Testing and Evaluation],Lightning Web Components Developer Guide Creating HTML markup and linking the SLDS stylesheet via static resource is also not a recommended practice for creating custom Lightning components, because it can create unnecessary complexity and duplication for the custom Lightning component. A static resource is a file or a collection of files that can be referenced by a Lightning component, such as images, style sheets, JavaScript libraries, or fonts. However, linking the SLDS stylesheet via static resource means that you have to manually download and upload the SLDS files to your org, and update them whenever there is a new version of the SLDS. This can create maintenance and compatibility issues for the custom Lightning component, as
