For iOS I think the only “automatic” option is Immich.

Nextcloud with the Memories app will be similar but I believe you have to remember to open the app when you get back on Wi-Fi.

Frigate can run in its own container and provide its own web GUI. You get extras if you integrate it with Home Assistant but if you think those aren’t worth spinning up an instance, then you don’t have to.

Blue Iris is another good option if you don’t mind Windows (blah I know but at least it’s still self hosted and fully under your control).

Stacher is a great GUI for yt-dlp on Windows and MacOS.

If you have relevant containers (e.g. the *arr stack) then you can bring all of them up with a single docker compose command (or pull fresh versions etc.). If everything is in a single file then you have to manually pull/start/stop each container or else you have to do it to everything at once.
