What 5 games would you recommend for the broadest possible sample of table top RPGs and story games?

If someone was interested in understanding as much as possible what the world of TTRPGs and story games had to offer, which 5 games would you suggest they play first, and why?

Ideally this would include a broad array of mechanics, themes and settings.
