As far as not taping the seams of the rigid foam - is that to allow any potential moisture migration up through, or is it just not necessary if dense packed below? Do you think I could cause potential problems with my initial idea using the rigid foam?
Not sealing the seams in the foam board would just be to allow for any moisture movement if at all required.
Also, it is not really required from the standpoint that they do not need to be air tight.
If you dense pack under the storage area, it is a not issue anyway.
