Yikes forgot one 🤦‍♀️

The light wood tone in your first pic says beach to me.

Can't vote as my first choice is not given even though you have it sitting in your kitchen. For beachy I would leave the white and find another way to throw money away but second is the lighter wood on the right in the first picture. The wood slab profile doors in the vote look "builder grade", something you would expect to find in cheaper apartments.

What's wrong with the existing white cabinets? I agree that white is a very nice beachy look. If I had to choose I'd select the lighter one on the right in your first photo, but then you have the issue that the flooring may not work well with it. You may be opening up a can of worms if you go with a natural wood cabinet.

White or the lighter wood. Consider replacing the dark cocktail table to a lighter wood.

Is the floor lvp? Is it up for change consideration?

I don't like any of the choices I think the light colored one might work but that door looks cheap . The floors drice many choices and real wood not one IMO.The one you forgot IMO will look like you treied to match the floor and missed . You have white cabinets in the LR why not the same in the kitchen? I think I need more info for sure . I also do not think just becasue you live at the beach the home needs to be beachy. Those really dark appliances sure do not say "beachy" I like the wall color in the LR but not the coffee table or the rug or the tacky little shelves. The kitchen from what I see is lacking storgae so wht exactly is the plan for the kitchen. IMO the cabinets are chosen after the plan is improved so maybe step back ans let us see the plan and get info. I think the TV is too high the coffee table serves no one so I am a bit confused as to what you are doing. Why a shaker door at all in th ekitchen I think maybe a nice slab door for a change .

Here’s some more info:
Our kitchen is falling apart, with door fronts coming off. I like our living room and intend to replace the coffee table eventually, but I’m procrastinating because I enjoy its style. The rug isn't a concern for me. We love the beach and surfing, which makes us happy, so incorporating that feeling into where I spend a lot of time is important. We'll move the microwave to the pantry and replace the oven and fridge. We have a budget, and since money doesn't grow on trees, we must try our best.
I'm attaching our work in process floor plan.

If replacing cabs, I would go with white - it will not create issues with your flooring and is a simple/classic choice

I too would keep the white cabinets. Swap out your cabinet hardware for beach glass in the colors you want to go for. Or if you are into shapes, perhaps shells or starfish shaped hardware.

That is not a floor plan a floor plan is a to scale drawing of the space with nothing in it all windows , doorways where those lead all marked and every measurement clearly marked thta is a floor plan Do it on graph paper posted here in jpeg format in a comment . Since you are asking for advice why not get it all. If the pics you posted are your idea of beachy I give up .

Patrica, you must be a joy to work with.

Price out Ikea Vedhamn European Oak cabinets, made in Hungary. Less plastcally than painted, imo.

Buy soon because of tariffs.

It might help if you found (or posted, if you already have some) inspiration pictures of kitchens that look beachy to you. I think light and bright for coastal, and I'm not seeing that in your mockups. But what's important is what beachy means to you.

Beesneeds has the right idea! White plain front cabinets with beach themed pulls would be nice and cost effective,also easy to swab down.Good thinking to get the micro away from range top location.Plan floors and floor covers to minimize sand intrusion...expect you will have a mudroom.While there is no requirement to overdo a "beachy" decor,it is good to keep things light ,bright and a breeze to keep tidy. Best wishes for an ideal upgrade.
