I would like to see a cabinet that is darker than the caramel but not as red as the cherry. I believe that you need a "richer" color cabinet to mesh with the dark rich granite (either color will be nice). Check out these cabinet colors:
Ward's Cabinetry Finishes and Specialty Options (AL) - Maple and Cherry Hardwoods, Door Styles, Custom Finishes, Stains, High Quality Frameless Kitchen Cabinetry.
I also live in Florida where the current flooring style in homes is either hardwood, saturnia (20 X 20 marble) or tile that "looks like marble". I would not change the flooring unless you were going to upgrade to hardwood or saturnia.
