My first thought is that putting the TV over the fireplace is not a good place, if you want 10 people to be able to watch TV at the same time. You are putting the TV on one of the narrow walls of the room, and there's a limit as to how many seats you can get facing the TV at a comfortable angle, because you only have 11 feet to work with. So you probably aren't going to like my suggestions, but I'm typing them out anyway. Sorry. Split the room up into two seating areas. Center one around the fireplace and one around the TV set, which will be on that long stretch of wall opposite the windows at the other end of the room. Put two chairs, one on either side of the fireplace, angling into the room. Put a loveseat or small sofa opposite them, facing the fireplace. A low coffee table or ottoman in between them. A small side table for one of the chairs, plus a lamp, either a floor or a table lamp, to create a cozy reading area. You could put a sofa table along the back of the loveseat/sofa for more lamps, or decorative objects, stacks of books or magazines, etc. You might also have room there for a small table and two chairs for playing board games or having a little snack or jotting a note or the like. Then in the "bottom" part of the room, either a great lounge-y sectional or a sofa and loveseat in an "L" formation, with the longer part of the sectional (or the sofa) facing away from the windows towards the TV on the wall. The short arm of the sectional (or the loveseat) would be in the middle of the room, with its back to the fireplace. A big, comfy ottoman in the middle would be a coffee table most of the time, extra seating when you need it. There would probably be enough room for another chair, either on the TV wall or against that half wall. The chairs from the game table could be easily moved if you need more chairs for TV watching. You can use area rugs to define the two separate areas. If you try to make the room one large seating area with the TV over the fireplace as the focal point, everything will need to be angled to that one wall, and arranging the furniture will not be easy. You could probably do it, with the right size sectional, but you will be left with a lot of "dead" space at the bottom of the room, which will seem to have no real purpose.

Consider creating a quiet gathering area for greeting guests and reading or working on a laptop in the area closest to the front door. Add in a couple of nice club chairs and an ottoman to put a laptop on. Maybe a credenza with an art piece over it on the solid wall on the right. Then I would get a feel for how many you want to seat in the TV area, and then determine what furniture would work best. I would start with a long comfy couch like the lounge by crate and barrel and then maybe a love seat and pair of chairs with an ottoman.

I definitely would skip the sectional sofa, just because it is so bulky and demands a certain layout to work in any room and is less flexible. Draw the room with the correct dimensions including windows, doors & stairs on graph paper . Consider any current pieces of furniture or rugs that you plan to incorporate into the room. Measure the pieces that you have and determine if they are going to work before you plunge into buying new furnishings. Decide what colors you love and how you want the room to feel and be used, I like to consider the rug including size and color first to build a room from the ground up. I love the light walls and the charming arch into the next room, so you have good bones to start and it will be such a fun project!
