Exterior door selection

I am currently building a studio and the exterior doors are double doors construction. one door will be a acoustic door, my question is for the second door. What kind of door I should pick up? Steel door, steel door with solid wood core, wood door? I prefer to have a glass in the door for natural light. Any specific brand you can recommend? Thanks.

Shesh. Give specifics. How much isolation do you want? What is the construction of the walls around it? How much are you willing to spend? How much are you willing to do yourself? Andre

the walls around it are double wall construction. see attachment for details. I will consider price up to $600 per door (I am referring to the door that in the sketch call for Andersen door), I will built what ever I need to built.
