I think Ubuntu is very good, if you want quick and easy. It's incedibly painless.
However, it does forced auto updates by default. They are called unattended-upgrades and run in the background by default. You can pause or disable them though. Also snaps auto update silently, by default. That can also be paused, though.
What really sucks is, if you don't have a printer it continues to try and install cups, which can be a security concern. However, I successfully blocked it by creating an immutable file where it would put the snap, while it was uninstalled.
