Sour cherries do well in shady sites. I have the variety "northstar" shaded by a spruce most of the day in similar climate in Chicago.
Also PawPaw particularly needs shade in early years. If, as other poster suggested, birch might be a short-lived tree, might be good site for a pawpaw (however, you will need two as they are not self-fertile)
