I setup navidrome but never got around to using it much personally. It seems like a good option for a private collection, but im more about sharing mine these days.

I setup jellyfin with feishin and use finamp on mobile for music.

Im running the latest alpha of funkwhale which i recommend checking out the stable version for a better impression but the alpha is functional if a bit ugly at the moment.

I discovered mstream fairly recently and really like its simplicity.

I have MPD setup to stream as a radio on my homepage.

Overall i mainly just use jellyfin out of convenience because i already use it for shows and movies.

I think if you already have jellyfin working navidrome isnt really as useful unless you dont like the way jellyfin handles music (wich objectively jellyfin isnt the best interface for music). Its not really that much extra overhead though tbh so you shouldnt hesitate to give it a try if you want to. Really anything thats just focused on audio streaming isnt going to add much overhead.
