You already have a lot going on with different colors - white, blue and wood. I just looked at that pendant today and it comes in other sizes. For some continuity you could order the larger version to go over the table. I didn't see the pendant in person, but the lady at the lighting store warned me that the black area is a weathered charcoal look and not a perfect black surface.

Me again, Tammy. Thanks for sharing all the photos of your cozy home. If you like it the way it is, just enjoy it. If you're wanting a more modern look, start two Ideabooks on Houzz, one "Transitional" and one "Modern Farmhouse." Save photos of houses you like that seem realistic with the style of your house--the "bones" of it, and what you already have. Look up something called "negative space." Here's an article on it in Houzz. It's about the nice sense of space and flow you get when your eye can rest on empty space. Not every wall has to have some little object on it. More space means you focus on a few nice pieces, an art work, some photographs, plants, etc. so your eye doesn't get too overwhelmed at taking in too many small things. That's why I suggested removing your metal shelves in the dining room to focus on your lovely hutch, whether it has a top on it or not.

Comments on your photos: --The bathroom is really nice--great paint choice; not too many knick knacks; nice shower curtain. --Sun porch: take off everything from the walls behind the corner wicker chair. If you want, add a little modern-ish reading light over the chair to suggest a cozy reading corner. One pillow--tops-per chair! How can you sit down otherwise? --Daybed/office room. If budget allows, a simple blue tailored print or solid cover would work better than the ornate spread on there now. Get a nice horizontal painting for over the daybed and remove the other little painting entirely and take off the metal thing. --Bedroom with brown tufted headboard. Hang the mirror and get yellow and blue curtains with coordinating yellow and blue shams and bedding. --Den with big brown couches. Move the sofas about a a half foot from the wall to add some visual space to the room. Move the the horse art to the window wall with nothing else--zero. That way, they'll be the first thing you see when you enter the room. Get a ledge shelf for the other wall and arrange JUST A FEW PIECES YOU LIKE ON IT! Negative space is a positive! Get a round tray for the ottoman in an accent color and leave it empty for people to put down drinks, food, etc. No pillows would be better than the floppy oversized ones on the couch that just look kind of sloppy. Less is more. --Fireplace room and everything that can be seen looks nice. If you have doodads hanging elsewhere in that room, take them down, so the focal point is that lovely fireplace. --The big bedroom. Move the mirror elsewhere. Center the dresser. It'll have more impact by itself. Again, doodads off the walls. Remove the little chest from the window. It's just another piece of visual clutter. You want a sense of the windows and light uninterrupted by that piece. Get some great curtains for this room and bedding that goes with them. With all the bitty things removed, these full curtains, hung very high and right to the floor, will have an impact. So will your nice bedroom furniture.

It is meant for a table and thats what you want/need so why not just put in a table? The space looks large enough that it wouldnt disrupt the flow in to your family room. A round table, even a glass top might give you the feeling that its still open. I think at the beginning it will feel like its blocking your family room because you have lived a few years with nothing there, but this is what the space was designed for and eventually, it wont feel like its blocking anything.

depends on how you live..your budget ..plans..etc, The dining zone in an open area can be made special/a destination with large pedestal table/ceiling fixture above/ really comfortable chairs and USE the seating for more than just mealtime. Or a smaller rectangular /drop leaf table can be pushed against the wall and your living zone chairs back into the space a little more because this is open. You could put a longer /narrower farmhouse/trestle table of a vintage sort with fun chairs/cushions and dress it all up for Holidays and so on. If that's a fridge [lower box], I might consider pantry cab adjacent and remove bakers rack, esp right now, and look at the whole space with different kinds of tables in mind...how each would fit in?, appropriate types for you folks? /etc.
