The best recovery option is the ability to snapshot a system and restore a computer or another computer to that exact state which has always been a thing even if implemented via rsync instead of zfs rollback/send. Gui installers offered a full disk encryption option when I started using Fedora 1.0. If you want a pretty gui Timeshift seems to be a thing. Power management in addition seems to work fine if the machine is properly supported. At least it seems to be as good on a thinkpad as on windows with more options via tlpui. Task management solutions are a dime a dozen.
