Try it both ways and see what happens. Maybe it is different one way from the other. Now you have two possibilities to create a picture you want. Or maybe it doesn’t make a difference in a way that matters to you.
The most likely way it will make a difference is mechanically.
One way is probably a little easier in terms of making photographs than the other. Maybe it is easier to turn the polarizer if it is first. Maybe it is easier to turn if it is second.
Maybe it is easier to compose and set exposure with one filter on. (or maybe not).
The right way is the way that works for you. Not what someone on the internet says…well except for this of course.
