I would do a chandelier and add 2 angled spots on either side to focus on the table. That's what I have and I think it's really sharp.

I am thinking possibly a painted table and chairs with a washed oak top? Would also delete the shelving to the left of the kitchen area and replace with long low console that you love....not to match the dining set, different and not oak or washed oak. Put your art work to one side of console and a lamp on the other side of console and a wide empty of vessel of some sort....consider changing out your chandelier and the black/orb knobs in the kitchen to Brass for a more modern look...bottom of chandelier should be 30-36 inches above the table top. Example of washed oak/oak table, console, chairs, and chandelier......

Need measurements of the space, but before you buy anything, remove the round rug and turn the table. The space is more generous than yours, but this picture shows what I mean.

You’re going to need a whole lot of lamps. I hope there are extra outlets. These rooms will be virtually unusable after dark. The ceiling height ensures a dim barely lit space. Unless you can get some wall sconces added, down low. Only there aren’t enough walls. The foyer is the real problem. Especially for a home for 55+. It’s a hazard where you can’t see. We need twice the lumens as young eyes as we age. A single pendant is not going to cut it. I’m not even going to start in on the fact that nothing about it is built as an accessible retirement home. If you ever need a walker or chair, you’re out of luck.
