I think that the pair are too small individually to work as coffee tables in front of that sofa. I also think that if you want two as coffee tables, you need to have two that are exactly the same. I love those little tables though, maybe you have another place to use one?

I would add a floor lamp on the left of the sofa near the windows, and a wood or metal coffee table with table lamp on the right side. The rug is nice, but everything is very dark and the same tone. I would use lighter colored neutral pillows, and large wall art with simple black frames.

Would it be too much putting our Christmas tree between the fireplace and hutch area? We are downsizing the tv and mounting above the fireplace. Please excuse the mess!

There is so much space, a coffee table is a fantastic idea, and an end table is the best alternative in congested places.
