Which Second Job should I get with each character?

1 ： Anonymous：2021/03/08 03:23 ID: m06nmm: I'm using

Vaan - Shikari

Balthier - Knight

Basch - Knight

Penelo - White Mage

Ashe - Black Mage

Fran - Archer

I was thinking using for second job Monk for Vaan; Samurai for Basch; And I don't know. What should I do? Samurai or Monk for Vaan? And which classes should I go for the other characters? I thought Black Mage for Penelo, but maybe a tank class?
