First you need clarity on product - what's being used where and what sheen. Then you need samples in each product that will be used on cabinets, walls and trim. These two colors are so similar, that a difference in product is going to matter more than usual. In other words, you can't judge or anticipate results - in this instance - based on color data values derived from paint color chips. Decided on cabinet color first and let that inform trim and wall color. Because you have the most limited choice with cabinet color.

Greek Villa and Modest white https://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6085-simplify-beige

We used BM Chantilly Lace with Taj Mahal in our kitchen. I tested all the whites and have large windows that face north in sunny FL. The Chantilly Lace was the sample that stayed white and bright in my space, while the other whites didn't. Used the same Chantilly Lace on all my trim, doors and ceilings. The walls are now BM White Dove, which is a warmer white and goes well with my furnishings, art, wood floors and stained beams. You will be fine! If you find things too white once you move in, all you have to do is repaint the walls in some of the rooms. I had picked a darker color to begin with, done by the builder, and have done my own repainting with the White Dove ... I'm not young anymore and my walls are 10 - 12 ft high, so unless you have a physical disability, it can be done DIY by the average person.

Sorry I've been MIA. Been super busy. So, my analysis of the DNA (scientific notation) of the colors we have been discussing is as follows. First, these all fall into a category of being able to "contrast" with the Greek Villa cabinetry. Greek Villa has a LRV (light reflective value)- or how light or dark a color will appear (0 being black to 100 which is pure white and reflects all light). Greek Villa has an LRV of 84. So very reflective on that scale. All the others that have been suggested are all in the 70-73 range. That means they are not as reflective so would give enough of a difference to be at least somewhat contrasting. HOWEVER, your light in your space both natural and artificial is very important to these values. Since you are struggling a bit with this, I suggest you consider ordering a "package" of samples the "warm whites" from samplize.com They have sets that are available and much easier to use than making your own samples and buying many sample pots of paint, poster boards, brushes, etc. and then having to dispose properly of left over paint. I use these all the time. I think the kit will really help you and you can see these colors much better in your own light conditions. Otherwise, we are just hunting for that "needle in a haystack". Hope that helps.
