I can’t answer your question as asked.
But I think that the 2020+ Crosstreks use the CVT F3 spec fluid. I believe that I saw that on this forum somewhere.

So what part number is that??

Maybe Bennie at Subaru parts can find out.
Seems strange that the Impreza and crosstrek use different fluid though.
