What a great room. Many good options but it would help to know what style direction your furnishings will be taking. Be careful how dark you go with floor staining. Trend is toward lighter woods. It also is important to develop furniture plan so you know how low you can hang fixture. If a large coffee table is in your layout it will probably be centered under chandelier which would allow lower hanging fixture. But if you hang one now, MAKE SURE ELECTRICIAN leaves enough wire up in ceiling to lower fixture later. You need 7-7.5’ from floor to bottom of fixture Min.

As aside, get the chimney inspected. There is a big problem with that chimney draw which is why there is so much blackening on the stone. Get stone cleaned before sanding wood flooring. Very messy to deal with soot.

I pulled a few to help you guide us to what style you are leaning toward.

Need size of room too. I figured it was about 16’ wide and 20-22’ long?

Fun project, it is hard to make recommendations not knowing what your style is or seeing the furnishings that will live in the space. Love the room with all of those windows.
