question: are most steel doors insulated & would you know what type of material it is? the reason i'm asking is if i screw up the door i may have to enlarge the opening that maybe more than i want to deal. i appreciate your thoughts
Mask the door carefully: I think I would make a stencil in a piece of plywood to cut through - if the cutter jumps, it won't ruin the door.
Cut it with a thin blade cutting disk in an angle grinder. The edge will need reinforcing. You could get away with screwing wood inside the edges, a glass insert can then be glued in place, and a trim applied by screwing into the edge bracing.

I'd expect they're insulated with polyurethane foam. It will cut easily, and doesn't support combustion.
Drill through the 4 corners of the square, to align the cuts by the way.
