If you want something that ‘just works’ on a framework, I recommend Fedora 38. Everything from the touchpad gestures to the fingerprint reader work out of the box and I didn’t even need to dig into the terminal to configure.
dnf is really easy to use and works similarly to apt. Apps and programs stay reasonably up to date without breaking anything, and if you need a more recent version, Flatpack is installed already.
Also in Australia, and I do boil when it’s rain water or ask the locals first before drinking tap water. Bigger cities are fine but small remote towns can sometimes have untreated tap water.
