I'll propose a floating sofa facing the tv. Then, a lounge type chair left of the fireplace and one or two accent chairs perpendicular to the sofa and sort of facing the FP.

Something like this arrangement. But, I think there is enough space to add a chair left of the fireplace.

I have googled a number of rooms with corner fireplace and wall TV and came up with a variety of floor plan/furniture arrangement that might give you some ideas to how you can furnish your room....a good place to start is to us painter's tape on the floor in the shape of your intended furniture. You can find furniture sizes on Houzz info sites to see standard measurements. Good luck!

Nice arrangement in accessories
