Hi dbosco
thanks for sharing your interesting project with us.
Please have a look at this article on how to choose between wall function and full-resolution modeling. as this will cost you way less cell, and computational time.
In regards to your mesh setup I would also suggest starting from a more coarse mesh.
You might can have a look at this forum conversation on how to approach such a mesh setup.
In the end the user was able to create a way better mesh with fewer cells, by optimizing the approach.
For your geometry, I would also suggest splitting up the leading edge of your wing, In order to assign a local element refinement here and a more coarse element refinement for the rest of the wing.
I hope these tips will help you.
Best regards
Sebastian
