15 D&D campaign opening premises I'm considering

Should I be a DM? If so, which of these would be the most fun to play?

1. Murder at a magic boarding school
2. The adventurers wake up in cave full of treasure, but don't remember the past two weeks
3. Advisors of a young princess who wishes to rule (in this one, I imagine many people to have secret goals)
4. An isolated town has lost contact and supplies from their liege lord. The party is sent out to make contact.
5. The rest of the town has fallen asleep. How can these adventurers save their town (or are they the ones in danger?)
6. All of the dead are rising, can the party help the dead get their rest?
7. A town's zoo has escaped. Can the party return all of the creatures and figure out what happened in the first place?
8. The king requires discrete protection for his lover out of town.
9. Two nations are newly in contact. The party is sent to discuss possible alliances and trades.
10. A magic-y Lewis and Clark expedition.
11. A sickness hits a town. The adventures are some of the few healthy left and they are sent to try and find a cure.
12. Heist to steal the crown jewels from the royal family. But who hired them?
13. A new queen fears being overthrown by her younger brother. She hires the adventurers to help quell a coup.
14. The team enters a baking competition to win coveted jobs in the palace.
15. The adventurers are sent by the very elderly kingdom librarian to collect and compose some special tomes.

(Prompt by me)
