Another picture of the room

That looks too far away from your seating to be of any use. Have you considered bring the sofa forward onto the rug?

Your sectional is like mine and I’ve spent days looking for a table that would be useful. I finally settled on a 35” square table. It can easily be placed within distance of the two-seat section of the sectional and not be too wide that it blocks easy access to the chaise part. So many rectangular tables were way too wide. Good luck!
