I used a Sherwin Williams Martha Stewart color on the outside of my house called Picket Fence. It is white with a touch of yellow, which makes it look like a warm (not cold) white. It actually snowed yesterday and as I was outside playing with the dogs, I was noticing how the white on the house looked so warm compared to the bright white of the snow. But it is still definitely white - I found that a lot of colors that were recommended to me had a lot of gray in them and looked dingy -- this doesn't do that at all. SW does not have the Martha line anymore, but if you called them, I bet they still have the formula and could mix you a sample quart. Here's a pic -- in the pic below, the paint on the porch post and along the eaves/soffits of the porch is the old "bright white" that we had on our house prior to painting. The body of the siding is the "picket fence" color. Hopefully you can see the difference - I know it's hard on a computer.

What's "creamy" to one is yellow or tan to another! Or even too white! I wish I could suggest a specific color but I really can't. Even though I probably have about 200 different chips of varying degrees of "off-white". I'm not familiar with the wall colors you have except I strongly considered Laura Ashley gold 2 for my bedroom. I recall that it is a complex, muted yellow/tan with green undertone. A really beautiful color. I assume that gold 4 is the same but deeper. I was amazed to see how a trim color can bring out the undertone in the wall or play it down; make the gold look either very green or more yellow or even dirty. So focus first on what undertones you need in your trim color. You already know you don't want blue, gray, pink/peach. You need some yellow but there are so many degrees of it. Take your wall paint chips to the color displays and hold them up--you will easily see which groupings of tones/shades don't work and you will be able to narrow down to the right family pretty easily. Wish I'd done that early on! You might also try taking your paint chips to Home Depot to use their scanner that will analyze your color & suggest coordinating colors from their line. That can at least get you started & when you start to see which tones are appealing to you the most when paired with your walls, you can take those chips with you to Lowes or elsewhere to look for the "just right" selection. Also, if you find a paint chip that has just the right tones but is just too light/white, (or the opposite, like if you wanted to use gold 4 but a lighter version of it) you can ask them to mix it with 150-200% of the colorant. Or cut it in half. I've done this with good success. All that said, I've just done the upstairs hall trim in Behr Navajo White, which to my eye when looked at alone is a creamy, muted yellow-- but looks great (and not yellow) with the several colors it needed to play with. And it took me many visits to paint stores, and many chips on the walls, to settle on my choice, but I don't regret the time I took now. Neither will you! Good luck!

We have cream/off-white kitchen cabinets and I painted our trim BM Natural Wicker to match them. I also had the same color painted in our master bedroom for several years.

@pink-peony, so pretty, are you doing the whole house with agreeable gray? I looked at that color a while back to re-paint the master, before the remodel started, why I thought it was a good idea to try and do a little project on my own leading up to a big one I don't know why (and by my own, I mean my husband would paint because the last time I did was a decade ago and it ended in tears). Any thoughts from folks about how to deal with the fireplace and walls in living room, I'm keeping it simple-no mantle, we have a gas insert with a decorative brushed nickel surround and an iron black trim.
