Sun films have been available commercially for a long while. Choose how much sunlight you want reflected (generally more in bedrooms that you generally want dark and cool, less in rooms where you want a view), and either get a professional to apply or do it yourself—it just takes a bit of soap water and effort.
Generally better to have the sun rejection happen on the outside of the window, so as little as possible energy gets absorbed.
What should you look at with choosing which film to get? Some mention more about insulating to keep heat during winter. I am mainly looking to reflect thermal energy during summer.
I’d go with a 3M product. Unless their quality has suddenly taken a shit, they’re best in class for that kind of thing. You want quality film because removal is an awful pain.

But you can’t wipe it off as easily as moldy yoghurt

You got me curious!
This looks like a start:

But then why is this a separate thing?

Anyway, there may be better brands. Do some digging first!
