In other words , if I find a set of wheels I like and order them 20/9/et18 and 20/10/et25 , would I get the exact same fitment ? As far as where the face of the wheel lines up with the fender ?
And as far as people with 20s rubbing, do you think if I went with a less aggressive tire width , such as 245f , 265r , it would possibly alleviate this issue ?

I apologize for the late response. I missed this post.
1) Yes, all wheels should have the same fitment when it comes to the face of the wheel's outer most point, and the mounting spot (inner most point).
The profile of the spokes could be wildly different however, and this is where brake clearance becomes an issue for some.
2) Yes, a lower profile tire would alleviate the issue.
However, it also depends on the offset of the wheel. As a lower offset would mean, more poke OR more horizontal push of the wheel into the fender at full lock.
For example this post has 265/30/20 tires on 20x9 et30.

However, with a 15mm spacer, his final offset is et15 which causes the rubbing at full lock, NOT due to vertical tire size increase, but due to the horizontal poke.
If the spacer is reduced from a 15mm to a 12mm, then he would end up with a 20x9 et18 which (increases wheel well clearance by about 3mm) would most likely alleviate rubbing.
