Dimensions of the space will help us help you with the size question.

A large round (48”) with a pedastal may work great and seat 6. If you get one with a 12” leaf you will have a 48” x 60” oval that will seat 8 - 10 depending on people size and chair size.

Given the door to the outside, clearance might be a factor, so size and shape might be important. I thought the attached article was very comprehensive and could help. https://julieblanner.com/dining-table-size-guidelines/

Tape out the different options and to see if both rectangle and round work (maybe oval also). Consider number of people to accommodate, if an extension would be beneficial, and any other criteria…then start your search. I’d go a bit more modern rustic vs Tuscan.

any plans for something on the flat wall?

if you don't need expanding room, I'd go for a glass top, you've got enough heavy going on in the rest of the room.

Sorry, the dinette is 12’6” door to wall and 11’ window to start of bump out. Door is 36” and opens in to the dinette.

I’d go with a nice, round wooden table….size TBD by your room’s size. Get one you can expand into an oval, as previously suggested.

A round table might work well. Here are some ideas for you:
