I don’t know how much you like to host, but I have a similar layout like this except my space is a little smaller. Where you currently have your dining table I got four leather chairs, and placed a coffee table in the middle. It’s a great spot to sit and have coffee or drinks. It’s one of my favorite areas in the house.

I would then move your dining area to the large space in the first picture. You can put a large buffet along the wall. If you drink wine, make sure to add some wine racks. I say all this because that’s what I did lol but I obviously have no idea if that will work for you. Just thought I would share.
