Looking at your pictures I have some thoughts to share. Whoever put in that hardwood flooring did you no favors. The original baseboards should have been removed and reinstalled after the floor was installed. The door jambs and side casings should have been undercut so the hardwood could have been slid under. That wasn't done. So removing the existing baseboards will be challenging, tedious, and time consuming. If you go this route, you don't have to lose the full 3/4" inches. You can install the baseboard flush with the top of the hardwood or 1/8 to 1/4 " below the hardwood. One thing you may run into is that today's baseboards seem to be even thinner than what was being used in the 1990's. That means you may have a larger gap between the hardwood and the baseboard for the base shoe to cover. It can also mean that the baseboard doesn't sit flush with the door casing (this would look OK, because it wouldn't be proud of the casing. Proud of the casing = bad). BUT, you have other options which would allow you keep your existing baseboards intact. One option is not to remove the existing baseboards but to add an additional molding profile above what's there. When it's all painted it looks like you have higher baseboards. That's what was done in these photos: This will substantially reduce both time and material costs and yield a great look. There are tons of molding profiles available. There's another product that's made that fits over your existing baseboards. I think it's still made, I've never used it. The challenge you'll run into is at the door casings - it will stick out further than the casings. The solution I've seen is to cut back the casing and install what's called a plinth block. All together it looks like this: Anyway, some things to consider.

What is the trim color in the rest of the house? If white, continue it in the kitchen. Bannister...post a photo.

There are too many decisions when you’re building a home (I assume it’s a new build, but even just a reno has so many decisions). Who is installing your trim? Sometimes you can have someone who is good with suggestions or can put together different profiles for you to consider. In general, you want your home style to coordinate outside and in. That’s why I asked what the outside looks like. From the windows, I am imagining something that’s more transitional - something between traditional and contemporary. It doesn’t look craftsman, but sometimes the simplicity of the craftsman profiles work well in a transitional home. Here is a guide to different moldings. It starts out very traditional, which I don’t imagine your house being. https://kelleher.com/wp-content/uploads/Catalog_Web_DesignGuide.pdf Here is another: https://www.metrie.com/the-finished-space/baseboard-styles For my personal home, I have shaker cabinets and went fairly simple with moulding. 9” baseboard with a simple chamfered top. No crown moulding. Built up window moldings (taller since there is no crown), but still pretty simple. Your cabinetry style can help inform your choices. Are yours flat panel or are those just paint samples?

Even if you paint the baseboards white under the cream cabinets, they will read a creamy color as they reflect the cabinet color and will be in shadow under the toe kick. We have been upgrading to taller baseboards as paint rooms with bright white trim. It's lots of work so i would not change it under cabinets for the slight difference it would make. The bright white does make those gorgeous wood doors pop and is a crisp accent to wall colors. I really like the warmer tone walls.
