I got the clear solar reflecting on my current car (all black) and it made a noticeable difference. I will probably do it again on my next vehicle. But since your cars are mostly indoors (unlike mine) I am not convinced its worth it for you specifically.We went ceramic last time and I didnt see a huge difference.
I don't get the windshield done other than the strip at the top. I believe that is illegal in most states.
But the two back seat windows are done by Lexus factory and I did the two front to match it.
New car as of a week ago or so, I will be getting the same, but will skip the ceramic most likely. With that said, both cars are kept in the garage unless I am at a Dormie property.
