Why can't you put a heavy (2 or 3 inch diameter) wood curtain rod right across the bay window and let the panels frame the bay? Take down the two prints to the left of the bay and you have plenty of room for full, lovely curtain panels on wooden rings. Select a wonderful curtain fabric and redo the seat upholstery on a companion fabric or a solid. Your dining room has a lot of elements that, taken separately, are all great, but they are not consistent in terms of quality or style. I personally like the chandelier--- it dresses up your dining furniture in exactly the way French country is supposed to look. But the fabric upholstery doesn't add anything. IMO the two elements that are way off are the unframed canvas---not nice enough for the room, and the mirror, which looks sort of "olde worlde Tuscan". Putting a bench in that window will block a lot of the light, and will not provide any really useful seating. Who would eat there at a tv tray or small table or with a plate in their lap when the others are seated at the table? So, I would replace the mirror with something bigger and square or rectangular and gold leaf and fancy. Put beautiful curtains on the bay on a gorgeous gold painted or gold leaf fluted rod held up with brackets. Reupholster the chairs in a beautiful solid color. Take the two framed prints and put them where the canvas is now (and move the canvas to another room entirely).

First consider seating needs/shape/size based on room’s dimensions and preference. https://nadinestay.com/dining-table-guide/ Did you want a set or prefer contrasting chairs. Is the dining space open to the living room, so having to consider its style. If you could provide more information and your budget and you’ll get more helpful suggestions, as there are so many options. Do your research so you can start to narrow down preferences and sources, save inspiration pictures (note lighting and art as well), but suggest waiting to buy until you move in.

I think a nice blue would be awesome , please get rid of the 1/2 dead plant and I think with the styles not all the same in the house you need to be careful that the spaces all work togeter using color and a bit of each in each space . I would look for amuch nicer chandelier for sure one that actully lights the table . If you go with the cahirs I posted alight with a touch of chrome could be fabulous

Here are a few photos of the furniture we picked so far (we don't have much yet) -- we got island stools, a kitchen table, and sofa for the formal living room. I also attached photos of the foyer/staircase that's right next to the dining room.
