I really prefer the half-height "T" layout in those size constraints but some people really hate it. It's an oddity to me: as you say, I'd be happier being able to easily feel out the layout and having all directions be the same size targets. Other than just not having the "look" of empty space I don't feel that there's really anything to recommend the "full height left/right, half-height up/down" layout. I wonder if you'll have more ability to play around in that space with the 16, as its top case is more modular. Part of the problem with the Framework 13 input cover is that the cover including the key gaps is all one piece of aluminum, so things have to work within those sized holes, or else involve a completely different input cover. (Edit: the 16 does I think have more theoretical room for alternate keyboard layouts, but of course that's assuming anyone makes them. More importantly, it just has the inverted T layout on the regular keyboard already.)
