Decisions like these are not made without knowing something about the furnishings or the rest of the home.

I have a concrete slab dining table with metal chairs- planning on a more transitional style.

We need to see more pics of room...how much natural light? Dark walls will suck light out of the room. Also pics of your furniture please. Do you have a rug picked out?

So I will be using a grey rug with yellow flower pattern. I’ll see if I can get a photo of my table as well. I’m trying to blend a traditional home with my “industrial” tastes. In the second photo, you can see 3 paint swatches we are deciding between for the top above the wainscoting. Barely visible is the 2 swatches to paint the wainscoting white. Thanks for your advice!
