You have a good point about tint in the rear. I don't have any and I'm not going to spend the money to install it on a 16-year-old car.
I agree that angled is the worst option, with sun coming in the side.

I think we're fairly close . . but I'd recommend experimenting with any vehicle. I'd include our SUV in the above (sun to rear) as no sun shade can fully block heat.
Plus that the front of the car is where the driver sits, the A/C has to in-take air, and that all the front sheetmetal is cooked. I vote to face rear.
And tint is cheap. My daily driver until a few years ago was more than twice the age of the car you cite.
