Right now I'm only able to find this board, Does anyone know if this board would work for me.
I noticed this is tongue and grooved. Is that okay or should i look for flat and squared?

Hello and Welcome to TFP!!
The foam board you want to use only comes unfaced. Yes, T&G is good. Be sure to triple tape the seams to prevent the liner from poking through.
Blue, pink, green are all the same stuff. Don’t get the foil face kind
