Get ready for maximum pucker factor. Deorbit, re-entry and splashdown still to come - splashdown scheduled for 8:45 AM EST. Re-entry is one of those things you can only simulate so well - eventually, you're going to have to enter the atmosphere at hypersonic speed and hope the math works out.

Fingers crossed.

I'm sure there must be some mathematical/physics or maybe logistics reason for splashing down off the coast of Florida and not in the Pacific right?

From what I understand, it's simply a matter of the Crew Dragon capsule servicing facility being in Florida.

Mission accomplished. For reals this time. I wonder what their process is for cleaning up the capsule exterior for re-use? Just scrub everything down in soapy water?

Crew Dragon won't be re-used (except for this one, it'll be used for another unmanned test). NASA wouldn't let SpaceX do a land-based touchdown using the SuperDracos as reverse thrusters, and it's not cost-effective to refurbish the capsule after a dip in saltwater. I'd be extremely surprised if SpaceX doesn't do their usual monetary efficiency bit and reuse the expensive bits, though.

Roscosmos just saw their business model fall into the Atlantic, too...

Would be cool if they re-used it and tried the SuperDracos. Another available contingency mode in case of parachute problems?

I would be extremely surprised if SpaceX hasn't worked out the flight controller programming already. Seems their style.

This particular capsule will fire the SuperDracos for a launch abort test.

Maybe they'll include it as a "ludicrous mode" hidden in some menu.

I believe the plan is to reuse crew dragons for cargo missions.

That's a good plan. Maybe fully re-usable will be the next generation goal? Although it seems like the X-37 already has that accomplished.
