Accessible beige actually coordinates well with all the fixed elements.

Then use it.

But I'm concerned it's been overdone and won't add appeal to future buyers

No one knows what a future buyer will want, or even if you will sell in 3 to 5 years.

For the best ideas, post images of your kitchen.

Take a look at BM Smokey Taupe. We are replacing our interior doors and painting them this color as we are ready for a change from white. Sampling on a sacrificial door it seems to go well with our edgecomb gray walls and medium brown floors.

Thanks! I'll check it out.

Id consider testing out these two:

I suggest them because your kitchen receives indirect light, so a lighter shade of your preferred neutral will help brighten the room due to it's lack of direct sunlight. Choosing something darker might make the space feel more enclosed and dramatic than intended. They both reflect more light than Accessible Beige.

If Accessible Beige is a good coordinate for what you have, investigate colors that work with Accessible Beige...for instance S W Dove Tail.
