A light colored runner, maybe off white, would look nice! This will make your table less stark. Adding a vase with flowers is a good idea. You can also put a vintage tray with flowers and different decorative accents on the runner in the center of the table.

When someone is sitting on the couch what are they looking at? I like what you have and agree with adding some color but I find the vase & grass (?) too tall and if sitting on the couch would have to be looking through the vase to something?

prob something like this. make sure your mirror is at eye level. current one is too high and too small doesn't have to be a mirror. you could do a gallery collection or one, large piece of art. put some leaves in your vase. You have the perfect wall to do some type of wall decor. either a shiplap, or wallpaper, or paint treatment, or millwork. something! A little bit of color would go a long way. some colorful art/decor items? maybe paint the inside of the cab this blue color if doing blue art? try painting the inside of the console a nice contrasting color, and accent it w/other decor pieces. (example, if you did a dark color like black on the inside, you could accent w/white pots, milk glass or lighter color items) This is a china cabinet, but you get the gist. framed mirror lean a mirror and add some lamps.

IMO remove the mirror and replace with a piece of art. Mirrors work best where they reflect something worth seeing twice and the side of a fridge is not it . Can we see the space from further back ? Is this a family entry or for guests ? BTW I will not go shopping for you that is your job.This looks to be a bit country the chandelier not so much so I really need to see more of your home.
