Personally, I would do a 10 AM flight and would not even be stressed out about it. Yes, sometimes things go wrong but most of the time they don't. We all have our own level of risk tolerance.
I would also mention that since Port Everglades instituted facial recognition walking off the ship WITH YOUR LUGGAGE and getting out of the terminal and into a cab is a breeze. If you are travelling on a non U.S. passport then pay no attention to what I just wrote.
