Changing the height of the tire affects gearing and steering geometry. A 1" diametral change for one tire equates to about a 0.5 degree change in steering angle if everything else is left the same.
Narrower tires tend to wear more quickly.

I never thought about that. I guess it is the same as raising the fork tubes in clamps.
I’ve always run a 120/90-19 on my YZ, this works well off-road but I’ve heard that guys use them on tracks as well.
At any rate going from a 110/100 to a 120/100 would result in .8 inch taller tire and the same amount wider (due to 100% aspect ratio). Taller sidewalls will soak up bumps better, wider tread should give better traction.
I could be wrong about the .8 inch but I don’t think so, if not that amounts to a bit more gearing than one rear tooth (50 to a 49).
