Kagi is fabulous. You can also use nextdns to block ads from getting in. They have a generous free tier and the unlimited is cheap. I have it on my router = ad free house.
13 years on Ubuntu deserves some kind of prize! It was my gateway into Linux back in 2006 but they started to lose their way with the Gorilla release. I like the look of EOS tho.
Arch is great. I used it for a few years back in the day, but it kept breaking stuff. I hear it's more stable now but I don't have time to be fixing things all the time.
Immich is on a par with Google Photos, imo. It's self hosted though, so not for everyone.
