To require users to choose a specific search engine from a picklist when lead source is "Search Engine", and hide it otherwise, the administrator should create a picklist for specific search engine on the same screen as lead source, and set conditional visibility so that it is only shown when lead source is "Search Engine". This will make sure that users see only relevant fields based on their input. A decision element will create an extra screen that may disrupt user experience. An assignment element will not affect field visibility. A validation rule will not hide fields but only show errors when values are invalid.

To track assigned licenses and permission sets in Salesforce instead of using a spreadsheet, an administrator should use User Report type on Report object. User Report type allows creating reports that show information about users such as their profile, role, license type, active status, login history etc. It also allows adding fields related to permission sets such as Permission Set Assignments or Permission Set License Assignments. For example, an administrator can create a User Report that shows user name, profile name, user license name, permission set assignments count etc. Login History, Lightning Usage App, or Permission Set Groups are not features that can be used to track assigned licenses and permission sets in Salesforce.

Making a field universally required is a way to ensure that the field needs to be filled on every record; it prevents users from saving a record without entering a value in that field. It can be used to ensure that the billing system field needs to be filled on every invoice record by making it universally required in the field settings. Creating a process builder to set the field, defining an approval process for the child, or requiring the field on the record type are not ways to ensure that the field needs to be filled on every record; they either do not enforce data entry or only apply to certain scenarios or users.
