Just my 2cents. I love your color swatches. Very coordinated and very pretty. I agree with the others that I wouldn't paint those cabinets. I love white cabinets and dream of having them one day, so I understand where you're coming from. But the thing is, your cabinets are so pretty that it'd be a shame to hide them. Cabinets are usually bought white, or are painted to cover subpar or ugly cabinets. The color of your cabs goes perfectly with the sample of granite in your pic. Also, painting cabinets is a big job. You have to paint the insides, as well (as opposed to refinishing the doors). I think the mahogany floors would look great even with you keeping your existing dark cabinets. The granite counter (the sample in your pic) breaks up the two large areas of red colored wood. The grays you picked for the walls coordinate great. However - and this is just a personal preference - I'm not fond of gray in kitchens, except for metal. Gray is a cool color. The color of metal. And your appliances are already gray, as will be your countertop. The gray walls won't add anything, and to me, gray is not a good color for kitchens. I also don't like the idea of a gray floor for the same reasons (unless it would be real gray slate or something along those lines). If you stick with gray walls, then I'd go very light gray or a grayish white, to brighten up the area. Benjamin Moore White Dove is a grayish white, I believe. SW and Behr also have grayish whites. Love the new lighting!

I would address the lighting first. Remove the fluorescent light and the hanging tiffany style light over the table. It looks like the kitchen is closed off to the other rooms of the house. That means you don't necessarily have to match the other finishes of the other rooms. I would get matching appliances (I'd replace the fridge unless you want all stainless). Then I would paint the wood trim white. I personally would probably keep the cabinets the way they are because a good paint job is going to cost some cash and that's not a project I would feel confident DIYing. If the cabinets are not in good shape then I wouldn't put quartz or granite on them. Since you don't have wood edging a handyman could put on new laminate pretty easily.

Agree with much of what you said. Forget painting the cabinets. Can you remove the backsplash and change it to something lighter?? Remove the scallop. Change over the sink light fixture. Maybe a can light?? Remove the appliances all over the countertops. As an experiment, remove every single thing off the counter tops and see how light your kitchen actually looks!! You would be surprised. The counter top appliances soak up an incredible amount of light. Is there someplace else they can go? A small not too deep cabinet in the eating area? Look at under cabinet lighting. There is some great LED lighting that can plug in.

My old farmhouse growing up as beadboard in the bathroom. I wouldn't recommend it. Even with "bathroom paint", it's just not a great environment for it. I think a fresh color of wall paint would be more effective and make the travertine look better. I don't consider travertine dated; I think it jsut depends on what's going on around it. You could also paint the chair rail the same color, if the white is too jarring.
