What's your favourite thing to self host and why?

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.

In that order.
Things like the *arrs, traefik/authelia, etc. are just a necessity and not something that gives back like the 5 mentioned at first.

what do you mean by “gives back”? To whom? For example, why Jellyfin over any of the *arrs

I think what they mean is that things like Traefix, arr, et al are means to an end. The ideal situation is that you don’t need to touch them after they’re set up. Jellyfin, on the other hand, is something you actively sign into and use
