I think most mobile/laptop devices should be encrypted by default though even that isn't sufficient with border crossings where you are better off wiping them IMO. They are too prone to loss or theft.
My desktop has no valuable data like crypto, sits in a locked and occupied house in a small rural community with relatively low crime (public healthcare, social security, aging population). I have no personal experience of property theft in over half a decade.
I encrypt secrets with a hardware key. They are only accessed as needed. This is a much more appropriate solution than whole disk encryptuom for my circumstances. Encrypting Linux packages and steam libraries doesn't offer any practical benefit and unlocking my filesystem at login would not protect from network exfiltration which is a more realistic risk.
