Currently using symfonium, does everything I need at least. Can’t speak for plex since it been years but it has most of the things you need, offline playback, playlist downloading and syncing, casting, supports transcoding etc. Plus it works with plex already so you can try it out (it’s free for a week then paid iirc but it’s well worth imho)
which apps? I tried jellyfin and plexamp works better than any of the jellyfin android music players I tried.

Give Gelli a try, I pretty much use it exclusively to listen to my music on the phone.
Didn’t find a good alternative for desktop yet though.
I tried it but had issues with offline content, does it work now?
