I think you are doing this backwards. It would have been easier to find the faucet and then the lighting.

Here are some inexpensive fixtures from Lowes and Amazon that might come closer to the finish.

It definitely would have been easier to do plumbing before lighting. But I found lighting that I loved on a great sale and just went for it. So here I am. I actually think that one you suggested from Amazon would be a good match, but they don't have the tub filler and shower systems available. The kohler Modern Brass might work. I just have to find some of these in person to compare.
