Unfortunately, most of the area around Coral Gables is either upscale residental/business or enviromentally protected land. And you're right, those parks you mentioned are simply city parks, meant for day tripping, not camping. It looks like Biscayne Bay is the closest car camping spot. The next nearest car camping friendly park would be the Everglades National Park, a fantastic park, but a bit far away.
