Most crafts are kinda death, atleast on Cerb. You can only make money with spending lots of money and much luck.
Gold is maybe the best to make money even when you NQ, but you first need lots of money to get there.
Cooking is annoying (since not much + with each Synthesis and sucky to collect all materials) but stable income, especially when you combine it with fishing.
I liked BC the most, while i know i cant get super rich with it, i liked it the most out of the crafts i took to 60 so far, so this was the main factor why i choosed BC past 60. Can easy farm most stuff and even make money while Skilling it, but as i said, cause i farmed.
Dont think you should choose your craft where you can get rich with. Just pick what you like the most.
You can search through the function here on AH to get a idea what synthesis you can make with each craft and what it chances are to make money with the
