You have already tried all the usual suspects. The ones you named are all colors I have tried or actually use in my house. IMO it's very difficult to find one color that looks good in every room of your house. If your home is not attached, you have rooms with all different exposures. No matter which color you use it's going to look different in different light. So you might love it in one room but not so much in another. I don't limit myself to one color. I have mainly two colors, one for the large south facing room (Pale Oak) and one for the rooms with the other exposures (Soft Chamois). Those two colors look fine next to each other. Soft Chamois brightens up darker rooms and Pale Oak looks livelier in southern light than in northern, but doesn't look yellow. Soft Chamois looks yellow in southern light. But I am also not interested in my walls being the star. I find these colors to be good backgrounds. However, I also have different colors in my bedroom (Edgecomb Gray) and the bathrooms (blue and green). Any bedroom can also be a different color. Think about which rooms are next to each other, so which colors need to be able to coexist, and which colors work best in the light you have. Maybe if you mix it up a little bit you'll get unstuck. Of course there are another couple dozen colors you could try also, but in my experience then you're going to get more pronounced undertones.

it all depends on how much natural light you have coming into each room.

if your floors are especially dark, and you don't have much natural light, I like BM Super White.

it is a fresh white with no undertones.

a great color to introduce great fabrics and patterns without compromising a neutral color.

get a sample, you'll be surprised.

Try B.M. Collingwood...a gray that can be a greige with different natural lighting.

A whole house color doesn't have to be a gray or a beige. What it has to be is a chameleon.

A very favorite of mine is B.M. Gray Cashmere. It is not gray! Well, it can be if you want it to be, but it leans blue or green...what ever is needed.

Pale oak sample is looking pretty good in my southern exposure rooms but cool in the northern exposure rooms. I was hoping to do all one colour but seems that might not work out

Collingwood and edgecomb are darker than I want. We don’t have quite enough light for them - hoping for something lighter but not white. Balboa mist is also too dark

Something between pale oak and Wind’s breath would be perfect but it doesn’t seem to exist

Gray cashmere isn’t quite the neutral Im going for, but it looks light enough!

I painted most of my house interior in BM Winds Breath and didn't love it. I had picked it because it looked great in my parents house. In my house in looked too yellow. I am repainting everything in BM White Dove. My trim is BM Chantilly Lace.

Thanks for your comment about whole house wind’s breath! It looks so good and cozy in my south facing bedroom but I’m afraid about the rest of the south facing rooms - your comment definitely helps.
I’m leaning towards pale oak whole house but it’s very cool in my north dining room. I’m afraid to do white, I’m really trying to keep the house feeling cozy.
