If you want to spend the money, Restoration Hardware now has a bath sconce that resembles a barn light. It tilts, too. They have it in bronze.
Condorcet Metal Shade Sconce

It comes in two sizes and three finishes. They have a LOT of metal-edged mirrors, as well.

Pottery Barn mirror/ ORB and sconce. It's not going to come as a "set" , hon

Not sure you why you are considering bronze when chrome or nickel would seem to be a better coordination with your existing selections. These items below from Wayfair

We're confused. What ARE your faucet, shower, etc. ? And is that the actual cabinet?

I like the silver look better, too.

Another thing is that bathrooms tend to have a lot of lint...from towels, toilet paper, bathrobes...lint kept all stirred up because of the exhaust fan. You'll be dusting dark fixtures every other day. Of course the same amount is lint is going to accumulate on a silver fixture but it will be easier to ignore. : )

My new walnut counter, windowsill, and shelves (where a med cab used to be) are dusty ALL the time! Ci_lantro has that pegged.

Black, not ORB
