The Zombie Stack Exchanges That Just Won't Die
Aren't most questions already asking 'What is the best way to do X?'
What does this tag achieve?

No, those types of tags should be avoided. Think of it this way —
It's not likely the question is actually about the subject of "best practices." Tags are supposed to tell you what the question is about (the subject of the question). Tags are not supposed to be used to describe why the question was asked, or similar types of meta-categorization.
So tags like [beginner] and [best-practices] and [subjective] are to be avoided.
