I think a black table with black chairs would be too much. Contrast is good. What size space do you have for the table? It’s hard to tell from the pic. Are you looking for round or rectangular?

Have you considered a round table that has leaves for extension to an oval table? This one might work! https://www.potterybarn.com/products/benchwright-extending-pedestal-table-seadrift/?pkey=cextending-dining-tables&isx=0.0.2919 https://www.potterybarn.com/products/benchwright-extending-dining-table-seadrift/?pkey=cextending-dining-tables&isx=0.0.712

not just the floors look yellow - everything kind of does perhaps because these walls are yellow! Can you paint them? I think going a neutral color on the walls would be a good place to start - like a very light taupe or greige look at Sherwin Williams Repose Gray or Mindful Gray. A bench along the wall under the kitchen windows would better allow for a rectangular table with chairs on the opposite side.I think a medium to med/dk wood would add nice contrast in the kitchen, but I wouldn’t go espresso dark. The drapery rods are hung too low and since you don’t have any drapes hung on L windows either remove everything or adjust the rods higher and hang matching drapes from all rods. I think LR rug will be too small for under dining table also. I’ll find some table/chair/bench options for you.

I think the lighter set would look fine, and actually more interesting than everything matching.
