ELI5: HPV is supposedly bad and needs to be cured - but I've also heard that it's not that bad and basically everyone has it. Which is it?

Both.  It's very, very common infection that in some cases leads to bad health effects, including cancer.  Only a small percentage of people who get HPV will develop cancer, but because so many people have it, that small percentage is still a huge number of bad health outcomes that could be avoided if everyone got vaccinated to prevent HPV.
