The other main difference is as sensor size goes up, you need to use a longer focal length lens to achieve the same angle of view across the frame. E.g., to get the angle of view of a 60mm lens on a "full frame" camera, a 40x54mm camera would need a roughly 90mm lens (with a larger image circle).
And as focal length goes up, the depth of field for a given size subject in the frame goes down at the same aperture...
