Loads of people here will help with your layout if you post a floor plan with measurements and note where doors, windows, obstructions etc. are. In fact, nice you put it on paper, you may even be able to figure it out yourself. Getting furniture to fit the scale of the room is important and having that with you when you shop is so helpful. As for upholstery, it depends if you’re buying it off the floor (more limited to what is in style currently) or if you’re special ordering (tons of options). What do you like? Do you have an idea book? Agreeable gray is pretty neutral and makes a nice backdrop for a lot of options.

We need to see if you have wood floors or carpeting.

I had a Pearce sectional in.pebble picked out from Pottery Barn, but it felt as though we were closing in the room too much. And now nor sure of fabric color.  My husband needs something he can put his feet up on. 2 sofas like we have?  Sofa facing tv with chaise attached or ottoman?  We have approx a 63 inch sofa right now. How much bigger can we go and how close to the fireplace is ok? 2 feer? It's a gas fireplace.  We want the tv out of the armoir and on the wall, but am afraid of just a TV console with that big tall wall.

Also , measure how far away from TV wall the seating should be in order to see it well— which depends on TV size as well. See if then the furniture arrangement will still incorporate the fireplace.
It might not be completely centered but still look ok.

I like that you are putting TV on wall, but in rooms where fireplace is too far along the other wall, people tend to keep furniture back by fireplace and a looong way from TV.

This is the problem with builders still making rooms with fireplace a centered focal point when buyers plan to use the room for TV. To me there’s an issue a when major seating is perpendicular to the TV and viewer has to sit sideways or crook neck. This is less a problem for fireplaces , which don’t actually need you to “ focus” on.

In a longer room the TV and fireplace seating can be separate groups, but I didn’t think from your measurements that will work here.

I’d enlarge up your floorplan and cut out little sofa & chair rectangles , also tables & ottoman and push them around. I’d play with that a lot before buying, as the arrangement and measurement specifics ( really knowing whether you can use 88” sofa or not, what size chair, etc) may spark ideas for which brands & styles you should shop.

So with our 13 inch wall, we should be ok putting g a long Media console like this one.
