What is likely the best job for an earth worlder in your opinion? And what would you attempt?

I've been racking my brain for a while now, and I think if I was able to get an alchemist or a blacksmith to take me on id likely never go hungry. And with how much we'd level compared to others, I think i could become a master work forger since id actually have ambitions and passion for the work. Then again the best cooks in the world are also on a similar level imo, and I can imagine Magnolia taking me in just because of this.
