The boys' elementary school did wrapping paper; the company they used supplied good quality paper. It was also made clear that this was something for parents to do, not kids. It was optional in support of some technology programs and didn't involve competitions or stupid prizes. Just "If you'd like to support program X, here's the web site for wrapping paper sales. Just use our school's code so we get credit."
For the whole school (K-12), the parents association sells scrip for a number of businesses. You buy $25 of scrip and the school gets a percentage. As an alternative, they have an arrangement with at least one supermarket chain so that by tying your loyalty card to the school, the school gets some money each time you make a purchase. (They used to use scrip for this chain, but the loyalty card thing is easier.)
There's a big fundraising event every spring. They rotate the activity. There's an art show one year and the next year they have a "cabaret," which is a variety show put on by students, parents, faculty, staff and alumni; I've avoided it for many reasons, but I'm told that the show is amazing -- there are some very talented alumni at this school. For each of these there's a silent auction and a raffle of some nice prizes that have been donated by families and businesses. We usually bid on a few items, although we've never won anything. (Actually, there are three events in rotation, but I've forgotten what the 3rd one is!)
Finally, there's a straight up annual appeal. Not too intrusive: We get one phone call and a couple of letters during the year. Some of the annual fund goes to teacher salaries and since my ex is a teacher, we don't donate a whole lot to that one. Nobody's complained about my $50/year. We donate so that the percentage remains high -- that's something that people giving grants look for.
Some of the school clubs (particularly the middle school) will do a regular bake sale or ice-cream sale at lunch to raise funds for their activities. My ex sponsored the animal rescue club which raised funds to donate to animal shelters.
There are no explicit sports or music fundraisers that I know of. I imagine that snack bar sales at games go to supporting the programs but that's about it. Students are expected to buy their sport "kit" (uniform, bag, warm up suit) and if they can't afford it, there's some financial aid.
I should note that this is a private school, so all funding comes from tuition, grants and fundraisers.
