maybe a rug, and some nice art on that wall.

whatever light you get, make sure it's about 36" up from the table. no higher

you could try a light like this

A washable flat weave rug (like Ruggable) would warm up the space, make sure it is big enough - I would also drop the chandelier so it's 30-36 inches above the table, select a fun and vibrant piece of art you love for that large back wall, and then add something you love in the center of the table would be great as well - a row of chunk black vases or something like that

I like the first one a lot. I think a tug with small kids might be a bad idea though ὠ5

that blank wall needs something. either do a piece of art or some type of wall treatment like a wainscot or a board and batten. look at farmhouse dining room pictures to get ideas

Let us go country style

Some quid for height

Perhaps try a rug, artwork, and a new chandelier. Here is a dining room design of ours which might inspire you.
