I think the window trim should match the other window and door trim, and baseboard, in the rest of the house. The cabinets are like furniture while the trims are the house.

I remember another member who had the same issue. I think in the end she decided that her white window trim didn't match her off white cabinets, was right next to it, and it was just fine. My light fixture (wood) is painted my trim slightly brown white, and is against the peachy whitish ceiling. In the right light you can see the difference clearly. Sometimes it all just looks white. It never looks bad. I think the thing to do is look at the two colors (trim and what you might prefer for a cabinet) as close together as they'll be IRL and see what you think. If its total gag time, don't do it. If it doesn't bother you as you walk by, don't worry about it.

If this were my project, I'd do the white kitchen cabinets and furnish the space before touching the trim. I'm not sure I'd paint all that trim. I now you are excited about the idea and having some inspiration, but give the idea some time and test it -- develop some other features first. The trim will be easy to address later, but a real mess if it doesn't play out the way you expect. I hear you about all that wood, but that's also all you are seeing without furnishings in the space. The listing photos had at least 2 rugs ad five pieces of upholstered furniture and chair seat cushions. The color and contrast faded the wood into the background and now in the empty or nearly empty room, it's all you are seeing. The room needs furnishing to feel welcoming and painted trim will not furnish it. And then there is the fact that I'm not sure you will get the look you want. There are a lot of differences between that inspiration photo and your space -- white vs. wood ceilings, beams vs no beams, number of window sizes and shapes. The inspiration room has a group of matching windows. Your room has so many different size and shape windows hung at different heights - even the doors are different sizes, and white paint on all of that will accentuate it. And start fighting the beams and other architectural details and whatever else you put in the room. Once you furnish the room, you may find you have a clown competing for attention and wish it would just fade back into the background. Do the kitchen, start furnishing or developing your plan for furnishing. Get rid of the previous owner's dark valances, chose something with some color, consider lighter fabrics and/or shades and work the room before you decide to tackle the trim. Instead of your computer design images, take an actual photo of the room and mock up all the trim in white so you can see the irregular sizes and shapes, the ceiling angles and beams and see if you would still go that route. Sorry it that is not what you want to hear, but I'd step back from the paint can for now.

Trim and cabinets don't have to match, but matching whites can be very challenging so it's often a smart choice to use the same color. I'd paint them Alabaster as well, it's a nice color
