I plan to install stone-coated steel or aluminum shingles directly on top of 4" of rigid foam insulation covered by plywood (no ventilation). A black 25 year asphalt shingle lasted only 11 years before it was SEVERLY curled which shows how hot the surface must get. Is there anything I should be concerned about using a black stone-coated metal shingle in this application?

This is a fine application. The shingle products that have an airspace between the metal and the underlayment will help further with energy efficiency. You may also want to look for a product in a lighetr color or with reflective pigment paint for even greater efficiency.
