"Just about everyone has accepted that the Sherriff's name is John"

That's just a fandom thing, though. I personally don't think the Sheriff's name is John. If it were, they would have just told us as much numerous times. As far as we know, his name could literally be "Sheriff."

It's like how everyone "just about everyone" thinks Stiles' real name is Mienim or  Mieczysław (the first one based off of the letters on the folder seen on Finstock's desk, while the second is just a guess based on "#MStilinski" and Jeff saying it's hard to pronounce and Polish when he was asked about Stiles' real name). Just because it's accepted in the fandom, doesn't make it true for the canon.
