When I Map Should I Use With My New External SSD In APFS Format?

what Scheme should I use? GUID Partition Map, Master Boot Record or Apple Partition Map. I am trying your method to download Big Sur on a new 256 GB external HD using the items you recommended.
Thank you.

    GUID. Apple Partition Map is for use with old old Macs. Master Boot Record dates back to 1983 and even though it still works, it has limitations, like not being able to boot with the drive on Macs, and having a 2TB size limit. GUID is the only one you need.
