@PugLove888 Yeah, I play on either long lifespan or aging off, and I often have my teens do Body Builder and Friend of the World... and sometimes Nerd Brain as well. I always set non-occult Sims to have Renaissance Sim as their first teen aspiration on age up for the Quick Learner bonus.
Other aspirations I really like and do a lot include Jungle Explorer, Bestselling Author, Painter Extraordinaire, Musical Genius, etc. Occult Sims who have aspirations (looking sadly at mermaids and aliens) always do the knowledge aspiration associated with their occult type. My spellcasters do both; my Vampires do Master Vampire and often Good Vampire (sometimes that feels out of character; Vlad would never do that aspiration, LOL!) Angling Ace is also fun, especially if your Sim enjoys cooking (and doesn't have the Child of the Ocean trait). I love the cooking aspirations but don't want all my Sims to be in the culinary career, so I can only do them with certain Sims. (I guess that might count for Renaissance Sim, though!) Ditto for Computer Whiz; I like it a lot but don't want all my Sims to go into the career.
I find the Beach Life aspiration very boring and repetitive but often do it in lieu of spending all those satisfaction points on Carefree. Oddly enough, the hardest part of that aspiration is on step 2, the kava party, which I find ironically stressful (since kava is supposed to relax you!).
I find Party Animal to be super buggy but the reward trait is great! (Basically, all events, including dates and parties, start at Silver.) Combine that with a great reputation from Get Famous and your Sim basically can't fail at parties. <3
