partition map scheme for external ssd drive with 2022 M1 Mac mini

During format/initialize how should I choose which partition map scheme for a 500GB external ssd drive with 2022 M1 Mac Mini running Ventura 13.0.1 ? i.e. GUID Partition Map, Master Boot Record, Apple Partition Map?

I plan to use this external SSD for additional storage of data files/photos/music as the Mac mini only has 256GB onboard.

I will use another removable device for my Time Machine backups as I have been advised to use a totally separate drive for them. Thank you, GroBo

GUID/APFS. If you need to also use the drive with an older (pre-APFS) Mac, then make it GUID/Mac OS Extended
