Score Voting or Approval Voting, yes. It's the only way to ensure—like mathematically guarantee—it's safe to vote for your favorite candidate _always_.

I am not so sure. I think there are other systems that can achieve this too. Eg a proportional system perhaps?

Anyway, yes, score voting is still a good idea if you can only elect a single candidate. People already understand how it works from sports.
