X-E4 vs X-Pro3? If money is not the main factor. Street photography.

I got the X-E4 as a more discrete compliment to my X-T4, and tried out both version of the 18mm, ultimately choose the newer f/1.4 since I intended to use it for architecture and landscape more than street, and the edge to edge sharpness is just better.  But the f/2 + X-E4 does make a wonderfully small kit, and just shooting street, the corner/edge/sharpness wouldn't matter as much. I think my (used) copy of the f/2 was decentered more than a bit too.

Here's a thread with some photos of the two 18's on the X-E4 and X-T4 side-by-side, and some sample photos of the lenses in action.

As far as the minimal controls on the X-E4, I adjusted really quickly, and I think I'll set up my X-T4 to match controls when I get it back from repair. (was supposed to have it todayk but, FedEx . . . different rant)

I have the single Function button(right of the shutter) set for MF/CF/AF changed via the front command dial.  But mostly I ended up changing it using the Q Menu, but that's probably because I only switch between AF and CF, when I want to use tracking, and so need to adjust the AF mode as well.

I control SS with the manual dial, mostly leaving it on Auto with minimums set.  ISO is almost always on Auto 1, 2 or 3, and/but can be controlled with the front command dial. One press and the command dial switch between ISO and SS control, for when the shutter dial is set to T(manual)on the dial, or to tweak it when I manually choose a SS on the dial.

Otherwise, I have the touch swipe funtions set to Timer, Film Sim, Shutter type, and something else I can't recall now.

I never really used the Q menu on the X-T4, since it has so many buttons to set, but I spent some time and thought arranging them (all 7, for custom film sims) on the X-E4 and find it really useful.

I've not ever held or used the X-Pro 3, but it seems that if you subtract the grip an SLR hump of the X-T4 they are pretty close in size.  I really love the form factor of the X-E4.  I used it with the 16-55, 70-300, 50-140, and I've never found the lack of grip or thumbrest to be a big issue, but that's me. I'd prefer the X-E3 body as far as that goes, but I wanted the flip out screen for waist level shooting and the extra film sims of the X-E4.

Gun to my head, I'd never give up the X-T4 IBIS if I had to choose one or the other, but I think if I had to choose between the X-E4 and X-Pro 3, and WR wasn't an issue(it would be for me), I'd take the X-E4 for the size factor. It really is almost jacket pocketable with the 18 f/2(no lens hood) and hanging from the camera strap around my neck is barely there.
