Based on your answers Closed Cell Foam appears to be the best choice for your project. 

Closed cell foam offers moisture resistance and a higher R-Value per inch than open cell foam. An additional benefit of closed cell foam includes increased structural strength in a wall system. Closed cell foam is a rigid foam that helps to glue and trap the studs in place therefore increasing the overall strength of a wall.
