IMO, if you're going to use Linux to manage your music collection, the web app options are your best options, unless you really like mpd for some reason (which is valid because mpd is nice).

Funkwhale, Jellyfin, and the dozen Subsonic forks/clones are better than whatever desktop music managers exist, and they have cross-platform clients so you can access your collection on your FireTV or phone.

There's no real reason to run any of them on Linux, though, since they're just web apps. Jellyfin and some others are written in C# using .NET Core, so they'd probably be more stable on Windows, anyway.
