You should consider Puerto Rico. The entire island has a small town feel, but the west coast is mostly what you describe. There's also great weather and tax benefits.
They lost 100% of their power network to Maria. Hurricanes are becoming more common and higher intensity. Humanity's days in the Caribbean are numbered.
Florida is actually a good argument about this. They have mangrove forests, highways, and railways. The islands do not. I was there for Irma actually - the amount of out of state resources needed for the cleanup and recovery was not negligible. The islands don't have those luxuries or the port capacity to keep up.
