I recommend using hibernate (suspend to disk): your computer will "sleep" for 10 years without draining. The only cost is about 7 seconds to boot on modern hardware. For short interruptions with instant wakeup, you can still use light sleep states.
It combines perfectly with LUKS-encrypted root and swap partitions: your data is safe even if someone steals your computer and swakes it up.
Hibernate doesn't work with secure boot/kernel lockdown for $REASONS, a lot of folks can't even use it. Supposedly if Linux can determine you're resuming from an encrypted partition it will work, but I was never able to get it to work with a swap file on BTRFS on LUKS
True, kernel developers should resolve the Secure Boot issue with hibernation, but the development focus is on servers, not laptop computers. Also, hibernation should probably use a dedicated hibernate image file instead of requiring a huge swap partition. That being said, it works regardless of hardware capabilities if you turn off secure boot and just configure a LUKS-encrypted SWAP partition. You should figure this out before you install the OS.
