I use Navidrome on the server side

Tempus on Android (maintained fork of Tempo)

Feishin on desktop

I also recently set up music assistant to try and stream my music to my TV too, although I haven’t used it yet beyond just testing and don’t see myself using it too much

I scrobble my Navidrome up to ListenBrainz too, which then gives weekly recommendations to add to my collection.
