IMO all the brass and gold colored hardware are always going to be hard to match and throw in a faucet and the whole thing becomes almost impossible . I dislike appliances with panels and why brass at all? I think this is going to always be an issue wth these finishes sine brass is an alloy and can contain different mixes to make up the color there is no way to get perfec matches form anyone for all the things you need . IMO stick with stainless for all of this and then add the brass as an accent instead .But it would help to see your kitchen and the choices you have already made.House of Antique hardware would have even more different finishes IMO than say Lee Valley for insrtance .

I am planning to purchase hardware from Corston. https://www.corston.com/collections/antique-brass-hardware. Company out of UK. More affordable than Rejuvenation even with shipping and duties, plus no sales tax. One thought, your faucet may be far away enough from your cabinet hardware to trick the eye. The living finish will kick in and perhaps not matter? Good luck.
