Steve, no. 2 is twist-o-rama.
Use a hidden cabinet hings (because they are adjustable) for the out swinging. Get Classic core plywood. Due to the MDF outer layers, they stay straight. Glue rigid panel in back due to its lightweight and that helps keep doors from twisting during seasonal changes. Will the area around the door be drywalled? If so, use a metal drywall J-bead, square that up during install and mud over that for that perfect finish. Make sure the gap between the door and the edge of the drywall bead is 13/32" and the 3/4" door will fit perfectly. Cut door to fit hole last once all drywall work is done
Use the none self close hinge (I like Blum) and a baby safety catch so there's no need to have a handle. Upon finish, all you see is a 3/32" gap.

In terms of sealing the gap for better insulation value, just use a rubber window gasket on the attic side.
