q: which run choice do i pick?
regular is the original mode, you will receive one random wind, water, fire, and earth job at each crystal. this is what i'd recommend for a first timer.
random will open up additional jobs for each crystal - any job that you haven't obtained yet that is also up for grabs. for instance, the water crystal may also unlock a new wind job instead, and the earth could hand you any job in the game. you're more likely to receive jobs from the first crystals as a result, and less likely to see an earth crystal job.
