I use FF on desktop with ublock, fb fence and various settings tweaked.
On mobile I use FF with ublock and the blokada app (which blocks trackers in other apps too).
In that setup I get great privacy results at the eff testing tool. Do you have other tools you like to test with?
Really not sure what to do about the fingerprint, but otherwise feel pretty good.
I think I tried brave at some point and it didn't do as well. DDG browser didn't do as well.
