Combat wheelchairs

[EggKookoo]

That is, I'd want the choice to play a disabled character to be significant, in a plausible way, while also being interesting enough that I personally would be tempted to play one for some concepts.

If it actually came up at my table I'd almost certainly play with the concept. If nothing else, the narrative impact of the wheelchair would be huge. It would shape a lot of how NPCs view and interact with the rider.
