Personally, I kind wish nearly every stuff pack came with a new event to help interact with and enjoy the new stuff we just bought. Spooky Stuff I think is one of my favs, just cause it came with a Spooky Party, the "playdate" event was one of the reasons I even considered getting toddler stuff, and the black and white party is basically the only reason I'm happy I got digital deluxe. It really goes a long way for me towards making me feel like the pack was worth the price. I get that not every pack has a good event to go with it, but there's been a lot of missed opportunities on that score so far, imo.
Luxury Party could've come with a Cocktail Party, where everyone shows up in formal wear and you have drinks and hors d'oeuvres. Perfect Patio could've come with a pool party event that included hangin' in a hottub and doing jumps into the pool as event tasks. Cool Kitchen stuff could've had an Ice Cream Social where you make and serve different types of icecream. Movie Hangout could've had a Movie Watching Party where you make popcorn and talk about the film. Romantic Garden could've come with a Formal Date option, which costs a little money but has fancier rewards, and where you and your date dress up a bit no matter where the date takes place. Hell, that could even be a formal "Proposal Date," for simmers who enjoy making that a bigger event! Like, you'd still have the option of proposing when and wherever, just like you can elope when and wherever, but the option for a bigger affair would be there. Kids Stuff should've come with a slumber party event, and that's a hill I will die on, lmao. Seasons wasn't out yet, but Backyard stuff would go great with a Summer Splash Party where you drink lemonade and use the waterslide. Vintage Glamour could have a formal dinner party, which costs more than a regular one and where guests actually show up in formal wear.
Those are all the stuff packs I have, so I don't feel qualified to suggest any for the other ones, but I'm sure someone could come up with things. But my point is just that having an event not only beefs up the worth of the pack, but it creates an easy way for the player to explore and appreciate the elements of the pack. Hell, I wouldn't be opposed to a "Spa Day" event for Spa Day, or some sort of non-date "dinner out" event for Dine Out, or, I dunno, a prom or graduation event with Parenthood???.
Anyway, I think I made my point. In answer to your actual question, I too really like charity fundraisers and would welcome gallery opening and book signing type events. Maybe if you were famous enough and good enough musician you could throw a concert. I'm another one who'd really like funerals. I'd also appreciate a "renew vows" or "anniversary" party, which would be similar to a wedding but for an already married couple. Family reunion would be another one, and also a "work mixer," where all your co-workers are automatically on the guest list and you can gain work performance from a success (tho this would've been good to go with GtW, now that I think about it...)
