We really need to see the entire room. My suggestion would be to bring the sofas a little closer to the corner. Get a square end table and 1 large lamp

Hoping these are the same size and not a full sofa and loveseat (they are such boogers to deal with and rarely attract more than one sitter.) If they are the same size, this may not be the best way to place them, but you don't show enough photos to be helpful. Looks like your art is placed where your former furniture was. It is most likely that your two sofas should touch at that corner and then you fill it with a large square table and your table lamp. The table should arrive 1" above or below the sofa arms. Hopefully, with the lamp on it you'll reach 58-64" above the floor. Hang the large art 5" above the sofa. Move the clock and the TV trays to the kitchen and remove the tiny items around the clock. Depending on what would be doubled by a mirror, you might look for one to put over the other sofa. You could switch the mirror and art in order to reflect something worth seeing twice, like a view or a pretty decor item.

The sofas can’t move any closer because the end seats all recline and would recline into each other.

So.... any ideas that don’t require me moving sofas?

A room divider or tall bookcase. These are nice examples.

Wouldn’t suggest white or teal end tables, as they will be too jarring. Without being able to use a coffee table, I think a new rug will be really important and that, along with cushions and art, will be all the color you need for a calm and pretty room. Have a vision before purchasing anything, so room will be well coordinated.

In regards to corner, a bookcase (keep accessories at a minimum like below) or tripod lamp to compliment your favorite lamp.

Then consider side tables: Large enough for lamp, but not too bulky. Consider only one, or both at other ends; see how it feels.

I’d decorate walls above couches differently and this could be a nice combination.

Put a tall plant in the corner with a gorgeous pot or basket.

Take down the wall art now, so you are decorating with a clean palette. The clutter is distracting in assessing a good layout for the lamps and tables. I like the lamps...they are kicky and you love them, so try to use them. The black folding tables feel a little too high and look tippy for the lamps, a book or cup of tea. Try lower and just a little bigger/substantial matching side tables that would better balance the lamps.

Your Grandmother’s lamp is fabulous! Do use it. Are you sure you want to paint it?

Hi, a corner book case is a good solution. Also you can consider a statement glass chandelier.

See image below. We have many glass pendant designs to choose from.
