In that case you would need to add the peers to the wireguard node you have running in the home lab as well. Wireguard can route peer to peer and will take the shortest path available to it.
That said, i highly recommend first getting things working in a “spoke and hub” style wireguard configuration with either your homelab or the vps as a central peer, then add peers as endpoints after you have everyone with working connections to the central peer. Its just a heck of a lot easier to trouble shoot and get your head around thatway.
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 also 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. My public service for funkwhale has the most users out of anything else i run so people def seem to like it.
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. But ive tried lots of dedicated music options and every subsonic fork still in existence, i keep coming back to jellyfin though.
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.
