You are now ahead on the OS (bookworm hasn't been released yet).

And behind with Samba, the latest is 4.17.4
I also cannot recommend using Louis's repo, it hasn't been updated for
quite sometime and it might never be updated again.
I suggest that you use Debian Bullseye and Samba from backports, this
will get you Samba 4.17.4

You are a bit wrong there, because you are using the 'rid' idmap
backend, all your AD users will be Linux users.

As you have only Windows clients, I suggest you set the permissions from
Windows, see here:
Because of the above, I would remove a few lines from your smb.conf:
acl group control = yes
inherit owner = windows and linux
inherit acls = yes
When creating your shares, only add the lines shown in the links above.
