I think a larger rectangle would work well. If you're adding colorful objects to the console, just be careful it doesn't get too cluttered. A few larger objects will look better than lots of little ones.

The problem I see with the newer one posted is that it kind of "matches" the sides of your table, making it look a bit too much like a "set". I think you can do better. The round one you have is a nice contrast on the finish and looks good with your wall color, but is just too small.

I don't have much time tonight to look for examples, but did find this. It's not a mirror, but I though the proportion and way it's hung looks good with a table similar to yours. Maybe others can help with examples; I'll try to look later tonight or in the morning.

I think this mirror could be a solution for your table.

You can find it at HomeGoods. Maybe Kirklands

I think most of their stuff is small enough that people fit it in pick-ups or SUV's.

But I did find this online: HomeGoods customers can get furniture and other large items delivered the same day. GoShare will send 1 or 2 delivery professionals with a truck or cargo van to help you load, deliver and unload your HomeGoods purchases. You can schedule your HomeGoods delivery in advance or on demand.

I think homegoods charges for delivery; seems like maybe they have a contract with a delivery service or something.

Look at Pier One, World Market, even Lowes or Home Depot for inexpensive mirrors.

My position is that contractors/workers/ builders ought to be punished for walls like that with all those switches/vents. Didn't intake vents used to be in the ceilings? Not pretty but at least they didn't interfere with hanging pictures!

Honestly, if that were my wall, I'd get a tall piece of furniture that would detract from all the utilities, like a bookcase or something with an open bottom like your table is now, with an upper unit with shelves. I'd put it a couple inches away from the wall to allow air to the intake...and I wouldn't care if people told me it would affect air flow - I don't think it would as long as the whole thing wasn't blocked.

But if that wouldn't work for you, what about some floating shelves above the table instead of a mirror or art? I think placement of one piece is going to be problematic with all the offset utility things.

Is that a heater vent blowing heat, or an intake just sucking cold air? If it's not blowing heat, I'd place a piece of furniture there, just not right up tight against it. I don't understand the advice to not place anything in front of an intake vent. As long as it's not right against the vent, it won't affect air intake. That's like saying you're going to smother yourself if you hold your hand 4" in front of your face. The air is not blocked as long as there is room for it to flow behind the furniture.
