Looking for advice on my family room

[blanda]

I'm planning on buying new furniture for my family room. We moved in recently and it has old furniture that doesn't really fit the room. Everything is up in the air more or less. The TV isn't permanently mounted (it's a 65" flatscreen FWIW). The only thing I'd like to keep are my tables/end tables. I'm a guy who's not a decorator so I don't really know what I'm doing.

I've attached a few pictures that I drew in CAD to kinda show what the room looks like and some things I was thinking. Room is 19'x20' roughly with 12' ceilings if that matters. There is a large window (highlighted in green on my attachments). The other entrances are archways leading into the kitchen/front of the house.

I'd appreciate suggestions on what sorta furniture might fit in here or if my current ideas are decent or completely crazy. I sketched out two options, one with a pair of sofas, another with a sofa/loveseat, other than that they're similar.

Thanks.
