Any advice on rug size for this room? 23'x23' great room/living room open floor plan runs from fireplace on one end to kitchen island (barstools not in pics - buying new) and opposite walls include a 3 panel 14.5' slider to the patio and an architectural cut out on the opposite stair wall (thinking a sofa table there). adding rug size pics in comments.

Also open to furniture placement recommendations. was thinking a side table between sofa and chair and use ottoman as "coffee table" with a tray
