If your kitchen isn't wide enough for shelves on that upper wall, another option would be pegboard for pot storage. You have to be ok with a "working kitchen" look. I used these for several years in the kitchen we just demoed. Four panels held A LOT of useful equipment that did not fit anywhere else in the kitchen. https://www.homedepot.com/p/Wall-Control-Kitchen-Pegboard-32-in-x-32-in-Steel-Peg-Board-Pantry-Organizer-Kitchen-Pot-Rack-Metallic-Pegboard-and-Black-Peg-Hooks-31-KTH-210-GVB/307440232?g_store=&source=shoppingads&locale=en-US&&mtc=SHOPPING-BF-HDH-GGL-D59H-029_029_HOUSEWARES-NA-Multi-NA-PLA-NA-NA-NA-NA-NBR-NA-NA-NA-Kitchen_Org_PLAs_Smart_Shopping&cm_mmc=SHOPPING-BF-HDH-GGL-D59H-029_029_HOUSEWARES-NA-Multi-NA-PLA-NA-NA-NA-NA-NBR-NA-NA-NA-Kitchen_Org_PLAs_Smart_Shopping-71700000093812048-58700007802254662-92700070907206010&gclid=Cj0KCQjw5ZSWBhCVARIsALERCvxPgsolZsn26q4NJbTw_FpuPVliYMALMGV5zZa5SR3n72by72fsW7EaAgskEALw_wcB&gclsrc=aw.ds

You say layout won't change but I hope you ditch that corner cabinet and the over the stove microwave for a proper range hood that's safer. Having an over a gas stove MW is an accident waiting to happen. :( As for the corner cabinet, you'd be better off with a cabinet that dies into the wall and keep the window wall open without uppers. Additionally if you make all your lowers drawers, you'll be able to store so much more in them, including your everyday dishes. I did all drawers in my new build and now I'm sold on how much more functional and easy they are to use. As for color, take a look at your wardrobe to give yourself an idea of what you lean towards. Is it the same as the colors in your house? If so, I'm guessing you won't tire of them in a few years. Or have you consistantly throughout your adult life used these colors in your houses? In the last 25 years, I realized I consistantly pick variations of the same couple of colors for my houses. The shades may change slightly but my houses have all been shades of tans, lighter greens and accents of reds.

are you showing what exists and must be replaced...or are you showing what you've picked so far..... nothing is too clear, Show the kitchen so people understand what kind of a space it is. Are you getting a knotty pine? do you have a door sample and a couple stain options. What maker are the cabinets coming from. Why are you picking pine instead of a recessed panel door in a medium oak.....that would be pretty easy. Pine is soft...tends to be orangeish unless there is a special treatment with some heavier pigment in the stain and glaze and so on. Pine can look good with blues and teals. I'm not saying dont get pine but the details to make it work can drive up your price..considerably. shown below: Knotty alder and 2nd is hickory ....much more typical now for a bit of a rustic look if thats what you want.

Can you post a photo of the cabinets and countertop stone?
