How about something different for the other end?

Before deciding on side tables, I would suggest that you try moving your furniture around (if you want to - lol). Have you tried your couch along the wall, add the art from console/turn horizontally and place over couch (if it's the right size), place console under the window, mirror where the console was and move chairs further apart. As you enter the room, it may feel more balanced as well as impactful. I find all you see with this set up is the side table and don't appreciate your couch or the room.

It would look nice against that wall but the sofa was placed there so you can see the backyard while sitting. I could try swapping the 2 chairs for the sofa and see how that looks.

matching end tables can set off a domino theory- matching lamps to follow & matching accessories. how about a floor lamp for the other side, something structural metal with circles incorporated, and a similar height table but different in design. i agree with Maureen. moving furniture away from walls creates visually more space. as per last picture with table behind the couch. (love the color of that by the way!)
