The list of notifications is in T333531: Temporary users should have default notification preferences.
The global documentation is at https://www.mediawiki.org/wiki/Help:Notifications/Types

A possible solution to ease this work would be to create a template that reflects the status of each notification for each role (regular account vs temp accounts)

Methodology

1. Update https://www.mediawiki.org/wiki/Template:Notification_type
   1. add a new parameter to display for "only for regular accounts", and a default "available for regular and temporary accounts"
   2. hide the parameters from being visible until the release
2. update https://www.mediawiki.org/wiki/Help:Notifications/Types to reflect the status of notifications for temp users as in T333531
3. When temp accounts are available, update https://www.mediawiki.org/wiki/Template:Notification_type to show the new parameters
