Thank you everyone for your input. My use-case for simple cli encryption is mostly for single files - not part of a full backup solution (for that I'm leaning towards zfs send with encrypted file systems). This is more of a one-off tar czf - $HOME | encrypt > /mnt/usbstick.tgz.enc type thing - or for sharing encrypted files. But I agree 7zip is a decent option for the latter.
