I'm installing a pre-hung exterior door on the back of the garage. The door jam is 4 9/16" wide. The total width of the wall (interior face to exterior face) is about 5 3/4"
The door jam is about 1 – 1 1/8" too narrow.
My question is where should I place the face of the door jam? Should I place it flush with the inside face of the drywall or place it flush with the exterior of what will be the face of the finished stucco?
Currently, it's just studs and sheathing. I'm looking for a best practice since I have options right now.
Wall Assembly
Moving from the Interior to Exterior
Drywall 5/8"
Wall framing 3 1/2"
OSB Sheathing 1/2"
Stucco about 1 1/8"

Bring the exterior edge of the jamb flush with the stucco. This will make it easier to seal against water. Not sure if exterior trim will be used, but it will offer more protection against the elements.
On the inside edge you'll need to rip a fill piece to make up the 1 inch shy door jamb. Glue and finish nail it to the (2) sides and the top of the door jamb.
