So far I know:

Endless OS/GNOME Software (renamed App Center) supports and enables auto-updates out of the box.

elementary OS AppCenter supports auto-updates, and prompts to enable them at initial setup.

GNOME Software itself supports app auto-updates, but I forget where it's enabled ootb.

From brief looking, KDE Discover does not support auto-updates? But that might be outdated.

There's apparently a non-default Steam Deck plugin for auto Flatpak updates.

And of course you could script it.
