Something skinny with a small footprint for the barstools. White with chrome to match your faucet or just plain white that can tuck entirely under the counter. Nothing with splayed legs to be a tripping hazard unless they splay to the sides and not into the walkway. For the living area, I would remove the glass piece full of sticks and put the live plant there. Find a table to fit in the corner created by the two sofas' arms butting together. It should arrive 1" above or below the sofa arms. Then add a lamp that reaches 58-62" above the floor when placed on the table. Lower the art to 5" above the sofa. Get a pair of "C" tables that can slip over the arms of the sofas so people have a place to put a drink or pull them in front to hold a device, or plate of food.

for the counter stools, do something that can slide under. nothing heavy w/a heavy back

these would be ok if they're light

sorry, but those two sofas won't work. (maybe if you place one of them against the slider.

like this one shows.

but something like shown in these photos would work much better ( just focus on layout and the size of the sofa,,,not so much the styling)

a sofa w/a chaise, like this, would be perfect. ditch the two sofas

get a nice console for under the tv.

you can shop around and find a vintage MCM dresser or console to use,

or, do something like this for extra storage and display

Both of these are Ikea hacks. first one used the Besta model. (if you look up, "Ikea hack for media console" you'll see lots of ideas

I forget which one this is (ikea) but they painted it and topped it with inexpensive wood boards, cut to fit.

Here are a few ideas for you:

And I would suggest going light on the bar stools. Also you could lower the tv a bit. Best placement would be to have the tv more at eye level to the sofas. And I think I would use a shelf/floating console type of piece there.

One more rug view. This is a sisal. The visual of your room just gives a rough idea of this one.

Using a common color thread is a great way to coordinate spaces: black stools and black console (with storage!) see set up below which feels balanced and more interesting. Add red to kitchen by moving your art to long wall in kitchen or maybe by front door, as stand:mirror feel a bit akward.

Create a layered feel in living room. Again bring in black, white and red: rug, cushions and art choices. It’s important to have a look in mind, in order to achieve a well thought out look, especially for a small space.

No one has mentioned the height of the TV. It is too high, and you need a mount that makes it flush to the wall. A narrow console for underneath to hold the "stuff" and get rid of the loveseat and replace with a small-scale chair.
