The plan separates each living space with access from a central hall. It would work well for an office building but not so much for a house especially f you plan to entertain. I find that trying to make a good plan out of a bad one is usually a waste of time and effort. Its like renovating a house that hasn't been built yet. Decide what you think an entertainment space should look like and develop the house around it. But I would not design a house around an occasional use. The interrelationships of family members should be the dominant theme of a house. And I would never put a level change in a living space unless there was an alternate wheelchair route. If you plan to entertain, the front door should have wheelchair access too. An accessible half bath would be good too.

I have no feel for the space at all a floor plan scaled and with detail would be very helpful. A new counter depth fridge would be my first purchase and please no more black.Is that just the pic or is there actually a faux finish on the walls, if so that needs to go for sure . IMO a glass top table with a silver metal base would be my choice from what I can see.

I need to see the space but usually a great room includes a DR so some pictures for sure .I have a DR table that seats 10 , we have a space that is quite open so whan we have a big crowd I move some furniture in my LR and our baby grand down and then add the other table base that we keep outside and put a piece of plywood on top and use white tablecloths to cover bot I have squeezed in 25 . I would need to see your to scale floor plan to really help.

Do you like branches' type? smth like this one? https://www.lightology.com/index.php?module=prod_detail&prod_id=771002 or this one which is less ornate https://www.lightology.com/index.php?module=prod_detail&prod_id=771028 they're gilded though..might be too much with chrome..chairs' legs are chrome, right? a bit hard to see.. this one is smaller but will have presence due to whimsiness and color https://straydogdesigns.com/collections/chandeliers/products/olive-chandelier one can go for several pendants in cool texture. https://www.etsy.com/listing/159724618/modern-pendant-light-custom-lighting?ref=shop_home_active_8&frs=1 way too expensive (as if other's weren't)), but I like te idea of customising every finish https://www.alliedmaker.com/collections/products/products/arc-pendant-perforated-20?variant=33462204873 these are cool but no idea where one gets them. to be frank. http://dmoch.se/news.html if you prefer industrial..one can order almost any length. I'm not sure where the light goes in this one though.. https://www.schoolhouse.com/collections/pendants-chandeliers/products/regent-chandelier-white many great links I had don't seem to work for me anymore(( but give us a direction maybe. Because I have a lot more that still work, and might be completely missing the point. whatever you have (is it Darlana?) looks good too I must say. I can see why you'd want a change, but still. great improvement on these shelves, congrats!
