I had only played vanilla, so picking the license boards was definitely the same feeling. picking the second board stopped my game for like a week.
my advice to myself would be just to pick what you like. you can get around any so-called "bad" combination, and the problem I found with most of the guides is they coupled classes based on a lot of end-game weapons and bosses. and so you play 70 percent of the game waiting on that part of the board or weapon, when other jobs would've been more useful or fun in the interim.
thankfully, they just patched it last week where you can reset your entire board (previously just an Xbox/Switch option, but now on PC/PS4). so you can get that Yagyu/Dark Robes combo whenever.
