Benjamin Moore “Feather Down” worked for me but honestly whites depend so much on your lighting that you really need to take samples to where they will be.

This is the same color with slightly different lighting

Led lighting comes in different shades of white from warm 2700k, 3200k, 3500k, 4000k and 5000k. What are you using?

I’m not sure if this was meant for me but the main kitchen is 4000. The white still changes color during the day as I have a lot of natural light (skylight, large window, French doors). The light in the pantry is currently 5000 but I’ll probably take it down a notch when we are done. But I sort of like having more light in the pantry. It’s going to have a small hanging light as well on a separate switch.

No one will be able to give you the "perfect" white. You have to test them in your own space.

I would never have used BM Chantilly Lace in my previous house as it was just a bit too white/bright for that house, but when I built, I tested all the whites in the new space. The only white that didn't turn dingy in my north facing FL kitchen was BM Chantilly Lace. For continuity, I then also used it for all the doors, trim, crown and built-ins in the house. Most of my walls are BM White Dove.
