A lot of homes in the warmer states are framed with 2x4. This allows for nominally R-11 insulation, which is apparently within code in FL. I assume NJ requires R-19, which requires 2x6 framing for enough space. You generally need to custom build a home if you want something beyond the building codes and lowest cost. For example, open or closed cell spray foam insulation.
Yes, block homes will need to be repainted at some point. Choose a top of the line paint and it should last a long time.

Another cost factor is painting stucco-was told if you et 7 years with builder line paint you're doing good
