In above, *all* those packages should be flagged as auto-installed -
because none of them are used directly, only as dependencies of
something more concrete.

python2 is not used directly on a FreedomBox: a FreedomBox user never
types "python" or "python2" on the commandline!
Instead, python2 is (or was in Buster, gone in Bullseye) used indirectly
by python libraries, which are used indirectly by daemons or other
tools, some of them depending on each other and others explicitly

My guess is you can get it down to 20 or less - a linux kernel and the
freedombox package and maybe nothing else.

If you are not familiar with apt and reading the man page of e.g.
apt-mark, then maybe it is not you but someone else more fluent in that
tool that should do such exploration.
Rather than start from a custom system already being poked with in
various ways, I recommend to start from a fresh install of FreedomBox
and try mark as much as possible as auto-installed without anything
I can dearly recommend to use aptitude in fullscreen mode for such
