Does it matter which direction I park to minimize heat to car?

I live in Florida. The parking lot at my workplace parks in an east-west direction. Depending on how I position my vehicle, my windshield can either face east or west. There is no parking garage available and no shade. It's an open parking lot with minimal landscaping. There is a 4-5 foot hedge I can pull up or back into, not sure if this matters.

If I work from 7am-3pm which direction should my windshield face to protect interior and minimize baking the interior and exterior, or will direction not make a difference? I have a sunshade for the windshield. I just purchased it and haven't had it long enough to experiment. I have been parking where my windshield faces east, reasoning that afternoon sun is the "strongest". I have a black car and black interior. I am concerned about my exterior paint and don't like it "baking all day".

There is a fancy car owner who arrives at the same time and parks facing west, facing the hedge. I wonder if she's on to something. Or am I completely overthinking this?

Park your front window West and use the sunshade. If you can crack a window for ventilation, even better.

Get your windows tinted. Between that and your sunshade, it won't matter how you park.

Face west, and use the sunshade.

When you get to your car at the end of the workday, use Technique Number 4 from this article: roll down the passenger window and then open and close your driver's-side door over and over (or just fan it-- you don't have to close it all the way). It'll give the cooler outside air a chance to displace the hotter interior air.

Your exterior paint really is made for this kind of thing. It definitely has a lifespan that's shorter in Florida than, say, a lifetime closed in a garage, but the car companies have been working on this stuff for 100 years.
