Doesn't answer your question, but I went with the Ford rubber mats for up here in New England (Massachusetts, US). First time I ever bought rubber mats and I'm completely happy with them.
I used the weather tech liners I had for my 2017 GT and they fit fine in my 2021 Mach 1. You also may want to check out Tux mats. They are softer and more flexible. I have the tux mats in my other car and I like how they are less ridged.
