Not exactly the same thing but I tried to use 5/3/1 rep schemes and % progression with weighted dips back when I was hell bent on not doing the bench due to shoulder pain - it just didn’t work.
I’d expect goblet and landmine squats to go the same way.
Some unclear points tho:
-are back squats still your movement for main work? Are you looking to do a different movement just for supplemental (eventually, why?) or to entirely replace main and supplemental work with a different movement (again, why?);
-what do you mean with long legs? I’m a dwarf but my femurs are very long compared to torso (which is what usually screws with the squatting mechanics), what would be your purpose? Do you want something that targets the legs more and forces you into a more idealized squat pattern?
-what’s the wrist issue you mentioned?
If you’re still back squatting as main movement and want to change things up for supplemental, you could front squat with straps as suggested above, if that option still bugs your wrists you could try the crossed arms stance on front squats, it should take your whole hand out of the movement. Something I’m gonna try due to the thumb tendinopathy I’m dealing with. Not a perfect/optimal option, but you’d still be doing an actual barbell squat.
