I'm sure that if you post pictures of your kitchen and the adjoining spaces, you'll get lots of feedback and ideas.

I don't know how open your kitchen is. I have a similar set up, with basically doorways between the rooms. So you can see, one from the other, but they're not really run together. I have the same hardwood floors in the entire main floor. I had a different hardwood in the kitchen before and it definitely looks better matching the other floors, and I think makes the kitchen look bigger. I have white cabinets, the counter is quartz (cambria roxwell) white, grey black and sparkles. Backsplash is silver metallic back painted glass. My dining room has a deep purple rug and bright colored artwork on the wall. The family room has multicolored geometric rug, a red leather sofa and a lot of really bright artwork. They really look fine together, but you're only seeing from one part of the other rooms into the kitchen, not sure if yours the same.

Sounds the same I will post pictures soon.
