Hello:
Using the latest mac os here, and need to know if this is better converting our External Hard desks to APFS or leave them As extended jornaled?
what will be the most healthy for my Desks?
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.

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:
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.
