IMO all these bronze and gold fixtures will soon be that dated look since nothing matches and never will . Eiter plan on mixed finishes or get nice chrome IMO a much nicer look than mis matched stuff all thrown into a small space .

You don't want to match it. Use a dollop of black, or white with a little champagne .....or black with a touch of the champagne brass......something else. Show the style of the Luxart you have, show the vanity, show an inspo picture: ) while you're at it.

There are lots of brushed bronze mirrors and lights on line. For lighting, try Shades of Light or Google, if you haven’t already. Mirrors shouldn't be difficult and I found this one quite easily.

Hard to be more helpful without knowing the look you are going for and the other elements, but also suggest mixing metals.
