This seems to work nicely now, good job!
I tested in in 16:9, here everythings is as before. The colliders are at the correct place.
Resizing does not change the bounds of the map.
I then tested in 16:10 and it finally works here as well! The bounds do not change when resizing.
This is how it looks now in 16:10, we get some black bars on top and on the bottom of the map, but i think this is absolutely fine.
