I would think that for doors like this, you want the horizontal pieces

One fastener per board, near the edge that's on "top" rabbet-wise, so
it holds two boards down without restricting expansion.

You'll need a diagonal cross-brace to keep the door from sagging, of
course.

Option B is to rabbet the column an inch or so across, so the door
overlaps the post more but won't stick if it expands a lot.

Oh, the 1x6's are tongue and groove.
