But I guess cutting dozens of 2" holes in wainscoting isn't really better than cutting 4" holes.

My first house had no insulation. Wood exterior siding. I did cellulose insulation blown in to the 2 X 4 walls. I rented a machine and drilled 1" holes between the studs. I dropped a fishing weight on a line to make sure the cavity went all the way down to the bottom. If it didn't I drilled another 1" hole below the blockage. Getting the right amount of cellulose moving thru the hose as a bit of a trick and the yard looked like a snowstorm had hit in September. To fill the holes I had drilled I bought a bag of 1" Styrofoam plugs that were sold for just that purpose. I dabbed matching siding paint on the plugs to protect from UV rays and to hide them. Eventually I stuccoed the exterior of the house and they were not noticeable at all.
