All film adds some level of interior reflection. Can be extra annoying on sunny days especially when you are driving in direction sun is facing.
Its illegal in most states to tint the windshield below the AS-1 line.
Windshield is designed to break a certain way if a body hits it. Adding film changes these properties. This is the main reason why IWFA recommends not to tint.
Windshield is single piece of glass cleaned most often. Odds of scratching the film is much higher. Scratched film increases optical problems.
Adding film (even Crystalline 90) will slightly reduce night visibility out of windshield.
I recommend you do your side/rear first. Drive car around for a bit before you commit to windshield. If you do windshield make sure you use Crystalline 90. Many shops like to use Crystalline 70.

I paid $450 for Llumar ceramic 15% back, 35% front and Air Blue windshield. I already have two cars with Llumar Air Blue on the windshield:
NO visible distortion. NO visibility issues. The HUD works perfectly. For the average person it's absolutely IMPOSSIBLE to tell if there's a film on the glass or not. The heat reduction in the car and on my chest/face/arms is tremendous.
