I am installing a wood stove pipe thru a SOLID block concrete wall (Has nothing else combustible inside wall) in my garage and need a product that is a hi-temp flexible sealant to seal around the stove pipe.

Would furnace cement be a good option or does it get hard when dried? What about some other type of fire barrier? The product needs to be flexible to allow for the stove pipe expansion of the tube when hot/cold.

Furnace cement will crack and fall off. If you must seal it, try to find a high temp caulk.
I commonly use 'fire caulk' to caulk around floor penetrations in buildings and have used it on sealing flue pipe also. It is usually red in color.
You can also use fiberglass rope.

Stove Pipe Sealant

Smoke shouldn't come into the room. Sounds like you have a negative air flow issue when you open the doors. Perhaps you need a longer up pipe or correct cap? Smoke means carbon monoxide. You need to get this fixed and I don't think sealing the pipe is your answer, you want the smoke and fumes to always go up the flue. Good luck and be safe.

There are several different furnace cements & sealants available.
Just go to some place like Home Depot / Lowes and pick one.
