I like white kitchens and I would like them whether they're "in" or not. My previous house had white Shaker style cabinets that were installed in 1997, so this is not a trend, or if it is, it is a very durable one. I will remodel my current kitchen in a couple years and will install white Shaker cabinets. There are numerous shades of white. My new kitchen will have to have a warm white because the windows are north facing and without at least a little yellow any color looks dead in this light. So bearing in mind where the light is coming from in your kitchen and what you like, maybe that will help you decide which way to go. While the cabinets are a large part of the appearance of a kitchen, the flooring and countertops matter. Having a different color island is popular and I like that idea as well. And it's easy (relatively) to paint an island if you decide you don't like the color in five years. It breaks up the white. First choose the cabinets, then the counters - are the floors you have now staying or are you replacing? All three of these things should coordinate. The backsplash and wall color come last. It sounds like you have done a lot of research. Maybe visiting a slab yard to see the countertop options will help you decide on a direction. The counter does not need to be white. IMO it is hard to do white with cream well as @arcy_gw said. If I were going to try it I would do the cream in the wall color so I could try multiple shades easily and change it later if I get tired of it.
Lastly, if you are planning on staying in this house more than five years you only need to please yourself. Sadly, anything any one of us does as far as decor is likely to be "out" in five years, or ten at the most. But if you like it you won't care. It's your money, so don't build a kitchen for someone else. I know BHG is not coming by my house anytime soon to take pictures, so I don't worry too much about what others may think. Here are some variations on white cabinets.
