[update]

I'm in a similar situation. Distro hopped quite a bit, (OpenSUSE, Ubuntu, Debian).

For 5 years now, I've ran Fedora on an old laptop that resides at my parents house, 5000 KM away from me. In that time I have not once physically been in contact with that server. I've done all updates via ssh, including full system upgrades (e.g. Fedora 32 -> Fedora 33) without any hiccups.

To me, that's amazing.

I've upgraded the Fedora install on my laptop continuously through Fedora 19 -> 33 without reinstalling now. That's about 8 1/2 years. Not bad at all.
