Don't go overboard with the acryllic. There is plenty of it already. Remember the purpose of a "coffee" table is a place to set down your coffee cup. Therefore, I think it should have more substance than acryllic so your room doesn't look like a show room for an acryllic manufacturer. I wouldn't mind if it matched the silver sofa table either. Center it with the FP, and draw the seating to it. I think once your seating is gathered around the coffee table, the navy bench will fit nicely at the window, behind the two chairs. Here's a run-down of what to think about when shopping (from Vern Yip of HGTV.) https://www.hgtv.com/design/decorating/design-101/10-tips-for-finding-the-perfect-coffee-table-pictures

I quite like what you have, and I also like its current finish. It has character that will translate nicely into a traditional style, unlike the other table pictured, which has a generic look to me.

That would work but I don't want to ship from New Hampshire as you point out. 😀 However even with shipping, it is still a relative bargain as Chairish has what appears to be the same table for $5500 plus $600 shipping. 😱 I am also reluctant to large items over the internet because I had a bad experience when the chest was defective and I was expected to pack it up and arrange for shipping it back. I would order internet through a design establishment because that is standard in the trades and my designer would have the relationship with the design house.

I think the room looks nice. And I really like the blue paint color you chose but it doesn't complement the FP. I would get an oval glass & brass coffee table. I would put the cabinet the TV is sitting on the wall where the pine cabinet is and get a TV stand that is at least 25% wider than the TV and a bit lower. It would fill the wall better. I would get it closer to the brown of the FP. I would prefer art over the FP because the mirror is reflecting anything worth seeking twice. If you move that tv cabinet, you could then hang the mirror over it and it would reflect the art over the FP. I think the chair would be better where the plant is now.
