Either can be done well. With block we generally recommend an insulation level of R-5 or more. Usually it is installed adjacent to the block and then a 3/4 inch air space is furred out on the inside. Make sure that the top of this airspace is blocked off from the attic. With frame walls the concern is good insulation installation and reducing air infiltration. Seal gaps, make sure insulation is cut correctly (too long and it tends to bend, too short and it misses spots). For specific detail drawings you may want to purchase the Builder’s Guide for hot humid climates https://www.eeba.org/mall/builder_guides.asp and for general guidance regarding design decisions, you may want to get our own Energy Efficient Florida Home Building manual http://www.fsec.ucf.edu/docsale.htm.

Consider finish colors that are light or white and
