Topic per title, basically.
For me: after setting up all the integrations and fall overs using the arr stack and Jellyfin (inc Sabnzdb etc)… I keep circling back to Nova video player.

It’s arguably not even self hosting…but there something undeniably cool about sticking a USB stick into a router, installing a single app on your TV and boom, done. EDIT: of course, it can consume the *arr stack, integrate with Ombi etc
IOW, I really like stuff that simple to set up and punches above its weight class.
I host a lot of things I use daily, but as far as really enjoyable, Navidrome. Like @BruisedMoose@piefed.social, I have a large physical collection of music that dates back to 1937 starting with a song by Lucille Bogan called 'Shave ‘em Dry’ and 'Till the Cows Come Home (WARNING: Very NSFW). I’ve been collecting for decades and everything is converted out to flac and resides on a NAS. I’m a mediocre musician on my very best day, but I’ve had a life long love affair with music, so Navidrome fits right in.
