post dimensions for the space it rests in as well as a few more pictures at different angles to get better help.

with those big windows and glorious light I would get a trestle table and push it against that pony wall with chairs facing the great room...and a chair on each end...If you brought the leather couch and two chairs in around fireplace as in a conversation, designated seating area ...you could get a drop leaf table and up against the wall where leather couch is, for "overflow' , to use as you entertain: either for seating or laying things out. People all live so uniquely these days ...some entertain , some don't, ...but I could get a secondary table that has flexibility in that room. As you say..tables are work zones, computer use zones these days.
