Ubuntu also has services like fwupd and unattended-upgrades that are configured by default to run periodically without asking the user. I do not know if there are any others.

Fortunately, as long as the user knows about them, they are fairly straightforward to mask with systemctl.

For people like me, who like having complete control and knowledge of everything their machine is doing, Arch GNU/Linux a good choice.
