Welcome Brad! The new XY Grid is a huge leap forward for grids in general so we're excited that you are excited!
There are many Foundation WordPress starter projects available and two of our favorites come to mind:
JointsWP - http://jointswp.com/
FoundationPress - https://foundationpress.olefredrik.com/
Both are similar and well made. Both are maintained by Foundation certified developers. I would start here as they are already integrated and include Walker themes for navigation and such.
You'll find written tutorials for FoundationPress here: foundationpress.olefredrik.com/category/posts
You'll find video tutorials here:

Looking forward to following your progress on Foundation!
