I don't think your kitchen is too busy---yet. But, it has a lot of elements that can take it that way if you aren't careful. The beadboard is a big part of that. It's an appropriate choice, but yes, I do think all of your examples are too fussy with the brackets and the beadboard. It takes away from the beadboard and the beadboard takes away from the brackets. I think that brackets or beadboard could work. Just not both. Doing floating shelves between the cabinets is very easy. Much easier than doing actual floating shelves! You can mock it up with cardboard boxes to get a feel for it. Basically, you are creating a large U framework out of 2x4's and facing it with plywood, mitered at the edges, or just filled with filler and painted if you want to paint them. The back, open U portion slips over a 2x2 cleat attached to the wall and screws to attach it to the shelf where you can't see it. Then you screw in from the sides of the cabinets into the 2x4 framing at the sides. A bit of caulking and touch up paint and you have a simple "floating" shelf between the two cabinets.

Kitchendetective, ty for posting this. I laughed til I cried reading about TP. I thought I was going to have to go back and put on a depends. Lordy, my kitchen will not be complete unless I have a happy face TP for my counter!

I too have Typhoon Bourdeux in our new kitchen( we move in 2 weeks) And while its a busy granite, I went with a ivory 3x6 subway tile in brick style turned out really nice, I was going for a clean look and wanted to keep our focal point on the granite itself also our cabinetry in kitchen is dover white looks really nice! I would keep your backsplash simple because the granite is really amazing..Good luck

@2ManyDiversions - The chandelier was from Lowes. Got a few matching ones from the same line for the dining room and foyer. https://www.lowes.com/pd/Kichler-Barrington-12-01-in-W-3-Light-Distressed-Black-and-Wood-Kitchen-Island-Light-with-Seeded-Shade/50356058 The grey "glaze" is sort of a grey highlight that goes in all the corners and interior edges on the cabinets.
