I keep seeing your question has not been answered. I do not build in the type of climate you describe but here are my thoughts: Do not trap moisture within the wall/ceiling structure- so one side only.

Follow the recommendation of the foam insulation manufacturer for how to finish the outside before you install your vinyl siding. Another good alternative is to blow in loose insulation. Since ...
