Extended journaled

If you plan to use Time Machine with your disks, leave them as extended journaled. Time Machine does not currently work with APFS formatted disks.

APFS and Time Machine

Just to clarify, although not initially supported, an update to macOS Big Sur added support for using a drive formatted with Apple's APFS filesystem as a Time Machine destination.

See: Types of disks you can use with Time Machine on Mac

Which says:

APFS or APFS Encrypted disks are the preferred format for a Time Machine backup

I have a couple of external SSD drives formatted with APFS, and both work fine - 1 for Time Machine and the other for Carbon Copy Cloner backups.
