There are too many to really point out any in particular. Here is an LGPO text file for my machine policies. These can be converted to a Policy Analyzer .PolicyRules file using LGPO.exe I believe to get more input as to what they are used for. You also have to add those policy templates (ADMX), which I have a few added for Zoom, Chrome, Firefox, LibreOffice, Office, Edge, etc.
