Bought a sunshade yesterday as well, see how this goes.
I would not be too concerned with UV. Most glass in modern vehicles will block a majority of the UV. I would be more concerned with heat. With that said Gyeon Preserve is such a good product. It does a better job than 303 in my experience. It also has less sheen than 303. Preserve has rejuvenated old plastic more so than 303. Gyeon nailed this product down. Works good to maintain rubber seals as well.
I would do a somewhat deep clean. Rejuvenate the plastics with Gyeon Preserve. Wipe weekly with something like Meguiar's Quik Interior Detailer. Then reapply Preserve every so often.
Tinted windows helps keep the interior cooler.
