Help with awkward living room space

Our new home opens up to this wonderful open space but the layout seems a bit challenging to get it to what we want to use it for. The pictures provided are from the listing and is using staged furniture. Ideally we want to put a sectional couch and TV in this room. I imagine where the large horizontal photo frame is in these photos is where we can see a TV being place. We want a large sectional but wondering how big and what’s the best configuration. On the other side of the living room is where a small dining area would be. The space in between also feels like an awkward spot we don’t know what to do with. We are very open to any ideas to try to get the space to feel cozy and cohesive.
