hard to pin down style

I'm putting in a bid on a post-war ranch house, with wood plank ceilings. It looks like you could shoot a catalog in it.

I'm having a hard time figuring out what kind of furniture I'd want in it. Easy to imagine Ozzie and Harriet in it, or Cary Grant with Myrna Loy, but that's not quite how I want to go.

Latest thoughts, triangulate between these:

Sundance catalog
Shabby chic (though shabby chic in general does not necessarily seem fresh to me.)

I love Midcentury, and that's around when the house was built, but it's hard to imagine the delicate lines under those big ole beams.

And this has me wondering if I should pull out of buying this house.
