Polarization filters only work, well, when you're about 90 degrees turned from the sun. It also adds reflections (off the objective lens) and degrades sharpness. It's more suitable for removing reflections on cars if you take multiple shots from a tripod. If you want a bluer sky you can do that in post.

Did you really think you were talking to someone that hasn't used a camera?

It also doesn't refute anything I previously mentioned.
