I've experimented with linux auto updates and the only one I found which easily and clearly worked while staying in the background was Mint. Mint seems like a modern lightweight equivalent to what Ubuntu was 20 years ago. Fedora might be second place with options between "do the updates ASAP but there might be weirdness if you're running something that gets updated" or "download and do a big install when you want to turn the PC off/restart". The bigger problem is that dnf-automatic and apt's automatic-updates seem pretty finicky to set up correctly and get feedback that it's happening, plus the documentation seems old and thin on the ground, it's just enough to cover the happy path and there doesn't seem to be any recent ongoing work. For Arch don't even bother because their attitude is that system admin must be handled by a human, automation for pacman isn't supported.
