Hey, welcome to the forum.
If I understand correctly, one of your issues with the keyboard is just that it’s too cramped for your larger hands? That keys with more spacing would be better.
If cost is not much of a concern for you, then you might be in luck. Framework has been preparing to release single key units, to enable the community to create custom keyboard layouts. community.frame.work/t/one-key-module-developer-program/78984. Once these are released you may be able to commission someone to use them to make you a custom layout with wider spaced keys.
