And what exactly is the problem?

Please describe exactly what you do, what result you expect and what
actual result you see.

You need

alias_maps = hash:/etc/aliases, hash:/path/to/mailman/aliases

where /path/to/mailman/ is the directory containing your aliases file below.

...

This is apparently a RedHat/Centos package distributed mm_cfg.py with
the following additions. (Also see <https://wiki.list.org/x/12812344>)

OK

Why this instead of the default 'localhost'?

Looks OK. but not referenced in Postfix - see above.

This is only used to aid in producing a more apptropriat default
configuration for the 'mailman' site list than the default.

It is intended that you run a command like

/path/to/mailman/bin/config_list -i sitelist.cfg mailman

to configure the 'mailman' list. sitelist.cfg is otherwise not used.
