Z-up right handed makes the most sense
Every kid learning math has to at the very least learn X and Y coordinates for graphs. That's the reason I think Y is the natural up, it just makes more sense to be in line with what everyone already know instead of flipping it around.
Imagine you’re drawing a level or a city or a landscape. Wouldn’t you want to work in X and Y for this? Precisely because you’ve learned the X and Y coordinates in school. Then you add Z as the height.
Yeah, for cases like maps it works, but most everyone that draws don't do bird eye view drawings. I'm just saying, I think it's more natural for people to draw scenes on 2D planes, and converting that to 3D Z as "depth" makes more sense. Although all the reasons I've heard for Z as height also makes sense to me now.
