Garage Wall and Ceiling Insulation Installation

Our garage has never been insulated, and it shows — in summer the space turns into an oven by early afternoon, and in winter anything stored out there gets close to freezing. I use part of it as a small workshop, and right now I can only work comfortably a few months a year. There is also a laundry room attached on one side, and I can feel the temperature swing through that shared wall whenever the garage gets extreme.

What I need is proper insulation installed on the garage walls and the ceiling — I am open to either fiberglass batts between the studs and joists or rigid foam board, whichever makes more sense for the framing and clearance I have. The garage is a standard two-car size with exposed studs on three walls and open joists above, so there should be good access without much demolition. I would like a vapor barrier included and the work finished cleanly enough that I could add drywall myself later if I decide to.

Requirements:
— Assess the garage and recommend batt vs rigid foam board for walls and ceiling
— Install insulation with the correct R-value for the climate and orientation
— Include a proper vapor barrier and seal gaps around outlets, pipes, and framing
— Leave the surface ready for an optional drywall finish, and clean up all offcuts and debris
