It might be good if keyboards were more symmetrical in general. Perhaps the Enter key could be in the middle, below the space bar, instead of on the right which might come from a vestigial bias towards left-to-right languages.

This is the closest thing I found just now by googling, though by similarly 'directional' reasoning I think Del and Backspace don't belong in the central column and should be on opposite sides: https://www.keyboardco.com/keyboard/truly-ergonomic-227-mech...

As well as enter/backspace/delete, it's also useful to have esc/tab near spacebar. https://github.com/manna-harbour/miryoku

Well. Then you'd need to move your hands, or stretch your fingers a bit. It's better to have a smaller spacebar key, to allow for extra keys.
