We tried it and didn't like the clunky UI.
We also tried Lemmy but it was a bit of a nuisance to maintain.
In the end we settled on a forum with a wiki.
We tried a few forums but in the end Flarum was the nicest, Just a bit of a pain to set the domain to be dynamic but it can be done with some PHP, alternatively, just use a reverse proxy with dnsmasq and wireguard pointing to that DNS.
As for a Wiki We have tried mediawiki, WikiJS And a couple others. I would recommend dokuwiki. (I hear good things about bookstack too).
I could never get mastodon to work with an app without using SSL.
I much prefer setting up a VPN and reverse proxy without having to deal with SSL. So it was really annoying not being able to use an app on the phone to connect to it.
