These are a few of my personal favourites. I assure you that their content is suitable And doesn’t promote anything bad.
PokeAK-a level 40 player in Alaska. His content mainly revolves around gyms and how to battle properly. He also does stardust sprees and reports accurate news.
Prodigies Nation-a level 40 player in Tennessee. Like above, his content is mainly gym based and (atm) is focused on legendary raids and how to maximise your chances of catching them.
Jonno Plays- He may be a bit controversial after the GoFest incident but his content is very entertaining. He usually does hunting videos (searching for 100 IV/rare Pokémon) but does other games like Magikarp Jump.
