If your wood pieces were painted in a satin finish in Black or white, or even white upholstery I am sure you could use a good deal of the pieces. In CA I see a lot of your style furniture painted in white, grey, black, or red -- Shabby Chic style in beach houses.
But I think Navy by the water might be a better look or some blue in the rooms.
Check out this blog for formal furniture used in a Shabby Chic beach house by "Beach Bliss Living" see her blog for some beach ideas shabbyfufublogspot.com Even though the furniture is very formal, the sofa is updated by upholstering it in white. This also goes with your Farmhouse look too.
