Hey fyi and for posterity, on SteamDeck I have the same issue and the cause is the same as outlined above (modern standby). I would love to hear more from folks who don't have this out of the box.
The fix is simple but I have to wonder why it's not set by default
Ideally the Steamdeck would come with hibernation after timeout and FDE enabled by default, but it doesn't. Still love it, and I'm glad/grateful it's open enough to enable these features on my own
