My house and shop has spray foam. Metal shed has closed cell, house has open cell. The closed cell (Shed) is about 1/2 inch thick and helps support the metal building.
The open cell (house) is 3 1/2 inch thick to fill all gaps before sheet rock was installed.
Both are great insulation but do some research on moisture and spray foam. I recommend you call several qualified HVAC companies and discuss what type of Heat/AC system you will need to ensure no moisture problems.
Sorry cant help on what spray foam is best, but I will never own a house without spray foam.
