my recommendation is to use 1 1/2 or 3" rigid foam cut to fit between the studs you put in the wall. You can use fiberglass, but make sure you seal up the concrete walls first really really good.

I was referring to sealer on the inside.
You can check unpainted concrete walls for vapor by taping a square of plastic to inside of wall... Tape all edges really good. Wait a week if moisture pops up, you need to do something.
I have used the drylock product you can get from Lowes or HD to paint inside of walls and works great.
IF YOU HAVE WATER entering the basement, you have to do outside work!!!!
When you say spray foam, what are you referring to?
For vapor barrier, the question I have is based on where you live, do you put barrier on inside or outside of insulation. Here in KC we do on the inside usually.
What type of wall do you have concrete or concrete block?
Sorry you have to dig it out. No fun at all. Last time I used a small mini excavator, and worked good to dig something like that. It was fun though.
Why not fill it up with spray foam? fiberglass is designed to take up full cavity (trapping air) so if you compress, it will not perform the same.
