Here is a closer view if it’s helpful

And the floor plan

What a lovely nice room view! That is a nice furniture layout for your family to lounge when watching movies. At the entry- place a mirror over the bench area amd wall art on the left (kitchen wall) Family room- a loveseat or second couch at 90 degrees from the first couch, plus a side table at their corner, and two arm chairs. Rug? -large enough to place all front furniture feet on the rug.

Gray white blue.... Any particular shade of blue? Indigo, spa, Aqua, teal,?

Since you have your color scheme in mind.... You have half the battle won. Keep it in mind when you are shopping. What is happening in your entryway or the first room as one enters the house? Is there room for wall art that can serve as an appetizer for your home's color story? It is something to keep in mind....

One couple had no idea of where to begin. They toured model homes to get ideas for furniture placement and a fluid color scheme. Then one day, they both spotted/ loved this wall art at a ZGallerie - Water Lillies 2 & 3 by Lilliana Purinton. https://www.pinterest.com/pin/228065168605625996/ and all fell into place from there. Like you, they started with a dark couch for the family room. They found a series of prints to hang above the couch (in similar colors Blues & greens- Zarris' Teal Ikat series. https://www.art.com/products/p26551596162-sa-i8116128/chariklia-zarris-teal-ikat.htm

Do you already own accent pieces that you intend for this space? Please post pics.

Hi DK Haas, thank you so much for your comments.

No, we will be getting everything new as our current furniture will go downstairs in the rec room. After reviewing the link to the transitional homes you provided I realized our style might be more modern. As I’m new at this it’s hard to say! But the tips provided work in either case.

What blue are you thinking.. Indigo, spa, baby sky, teal, Aqua ?

Is there a store that captures your style? Pottery Barn, Restoration Hardware, Z Gallerie, Ethan Allen, West Elm...or other- Import store?

..???

Oh great question! I like LD shoppe https://ldshoppe.com/ , Eclectic Goods https://eclecticgoods.com/ and West Elm

My must haves for a living room: comfortable sofa that's long enough to nap on, but not hugely deep; generously-sized coffee table or coffee table/ottoman; recliner for any man who resides or visits; a side or end table for the man in the recliner so he doesn't have to move far to reach TV remote. For me, everything else gets added after those key pieces are placed.

The LD Shoppe link led me to their design services, where there are inspiration rooms you might like https://www.leclairdecor.com The LD shop website is strange as it's just a catalog of interesting items, but doesn't show you rooms to help you

Sadly, I cannot get the Eclectic Goods COLLECTIONS section to load ugh!

How many will regularly use this space and what for? TV, family table games, cozy fire watching, reading, entertaining guests, enjoying the view? You can zone it for all of these activities if you want. Swivel chairs can span the different zones so they're more versatile and can flex for your needs. A 3-seat sofa is always a winner.

Thank you @DK Haas, I will take a look!

@decoenthusiaste, we will be using it for all of the above activities. We are a small family of 3, but will have friends and extended family (3-5 more) over from time to time. Swivel chairs are an excellent suggestion!
