I have no real preference. Even the vague goals have some level of clarity to them, Pokemon Breeders pretty much just take care of other people's Pokemon. Generally, all the goals are basically being the best at something. S-Rank Sommelier is just being the best Sommelier, probably need years of experience. I feel they give enough info for people to draw reasonable conclusions about the goals. Pokemon generally likes to keep things open ended too so there's never really any intention on having these goals laid out right in front of you, they want to get the message across that goals are ever lasting and you'll have to work at it your entire life, not spend a summer and become the greatest thing ever.
I do like goals that have a clear path and get flesh out throughout a series, but I like open ended stuff too, so really, I'd take whatever they give, I'll enjoy it either way.
