A lot of my characters didn't necessary chose their career but had it chosen for them. Malina, Aca, and Zabar all had their careers chosen by the family. Malina was quiet explicitly forced into becoming a huntress by her parents before she caved and went with it. Aca was forced to spend most of her time with her dad, not that that's a bad thing, because her mom spent all her free time with Malina. This made her pretty much exclusively exposed to hunting. Aca was pretty set in stone because of her exposure and exclusive exposure from a young age, but even if she wasn't a huntress, Malina would have probably gone into aura tech research.
Zabar was born the youngest of 5 and the four before him were either scavengers or hunters. His only real options were Scavenger, Hunter, or Politician like his parents and grandfather and it sure wasn't going to be the latter. In another time, maybe, when the world wasn't as advanced he may have wanted to be a cartographer, but in this time his two options were scavenger or hunter.
Titania and Brook are the most likely to have other options if they could go back. Titania would have probably become a botanist or something similar while Brook would have followed in Phaedo's footsteps and tried to get into the political world to help faunus.
Phaedo and Kol, on the other hand, were never going to be anything other than what they are. Just like Malina, they had their ending point chosen for them a long time ago.
But none of that really matters because it's where they all are now and that's how it's supposed to be.
