I just like actually owning all my stuff and don't want to deal with sites randomly shutting down, moving, having an incomplete or miss-organized library, bad quality, etc. My own collection certainly isn't prefect but if there is issues I can fix them, it's all in one place (no different sites for movies, tv shows, anime, music, etc) and it tracks all my watch-history which most free sites don't. I can one-click download stuff to my laptop or phone for offline-watching (guess you can do that with yt-dlp for most sites, but again more effort)

Are you hosting arr stack/plex/jellyfin?

Yup.

How much is it utilized (in watch hours/week for example, mine was less than 2/week)?

I get about 3 days of watch-time between my 10ish active users per week.

Have you considered not using it?

Nope, I'm so done with the free streaming site whack-a-mole, not going back.
