I would put the wall cover on one side then use friction fit rockwool or fiberglass.

What are you looking for the insulation to do?
Sound, temp, and/or fire control?

Mostly temperature & cooling to match more closely the main house during the winter and humid summer days. I'm calling it an "office", but it'll still be part of the garage.

Caulk/foam seal framing top bottom plate to seal any garage smells from office. Fiberglass then continus sound barrier on framing.

Is the ceiling insulated? That's where your heat loss will be. Insulating the interior walls won't really help with temp control unless you are heating/cooling separately.

Yes, the garage ceiling and all three walls are insulated as well it has one of those thick factory insulated type garage door. The garage itself is unheated, but never gets below 40 degrees during the winter. I have a small portable 1500 watt heater that pumps the temp up to 60 degrees when I need to work in it. Once the new wall is all finished and I install a door, I plan to just leave the adjoining gray door to the main house open for general heat and A/C when I'm home, which is 90% of the time.
Must be really tightly.sealed if a 1500 watt heater does that!
I have 2 in my ~15x20 office in the warehoyse. It'll barely keep it 70 when it's -40* outside. And that's in a 60* building.

If I go with R-11 fiberglass insulation, do I get the one side paper type or the non-paper type? Should I staple plastic sheeting facing out into the garage also?

Its an attached, single car 12x22 garage with one window on the outside wall near the garage door. Very good sealing overhead door.

I'm going to use these Dricore 2'X2' panels on the floor and probably cover it with indoor/outdoor carpeting and a couple runners which should help keep any dampness out of the office space. 
How big is the office?!
I was imaging something around that size for just the office!

Very small 'L' shaped, one half is 6x6 and the other half 6x9.

Any insulation will work fine here. I like the rock wool suggestion. And for the 100 square feet, a 1500W heater will be plenty. Back in the 70's with poor insulation, the seat of the pants calculation was 10W/ Square foot when heating a house with electric heat. Here in central MA. (my father did hundreds of houses with strictly electric baseboard heat in the late
60's/ early '70's) Back when electric was desirable. Oh, but now it is again.....but I digress

Get whatever you can find cheap, not need to do faced but my local home centers don't stock unfaced. It really won't matter much which side the facing is.
I would recommend drywall on both sides and make sure the door you put in is a sealed door, basically an exterior style door with threshold and weather stripping.

Mineral wool! More expensive but it's easy to install, fireproof, lots of sound deadening and it doesn't get moldy like fiberglass. It will be a long time before I even consider fiberglass again.

This. Also mice love fiberglass but not mineral.
