Can anyone tell me if it really matters if the overall
thickness of the wing is off by a few thousandths...

Based on template checks of several top-ranked contest ships, I will
opine that it does not. For a few of the ships, you'd guess on the
basis of the template mismatch that the right and left wings weren't
even for the same aircraft. And yet these were all straight-flying,
go-like-stink gliders.

So you'll find me in the camp that says that waviness below .004" is
first priority, canopy and wing root sealing is second, and fidelity
to profile is a distant third.

Thanks, and best regards to all
