My two cents: The Keychron Q11 is a decent choice for a split keyboard which also has a traditional layout and therefore doesn't require any learning. If you don't like the distance, you _can_ push the pieces back together and they'll just resemble a traditional keyboard. And it's definitely the highest build quality of any keyboard I've used this far in my life.
It seems to have this issue (or maybe Macbooks do? I don't know..) where, waking my computer from sleep, the right side of the keyboard doesn't work. It's quickly fixed by unplugging and replugging the right side of the keyboard into the left, or unplugging and replugging the entire keyboard into the computer.. it's a shame that I have to do that sometimes, though.
I have the Q11 too (and I fully agree with your appreciation of it), but I'd like to say that I never had this issue with the keyboard. I _do_ have it connected to the laptop (tested both on a M2 macbook air and a M4 Pro macbook pro) through a `ThinkPad Thunderbolt 3 Dock Gen 2` -- not sure if that may be what's avoiding your problem.
