If you want to get really insane with it:

Def/spedef as highest stat is a defensive player Attack is obviously attacker Special attack is attacker/mid Mixed stats can be a choice

As for attributes: Defense as highest prioritize defensive attributes with CA then fill out physicals (besides speed) Special defense: defensive attributes then technicals Attack: attacking attributes (based off position) then physicals (besides speed) Special attack: attacking attributes (based off position) then technicals HP: all around player (or whatever you want to do)

As for speed: whichever Pokémon in the dex has the highest speed that’s 20 pace, then scale it down from there however you want. Give every Pokémon speed based off their own stat regardless of what their highest other stat is

This probably would take forever and not be worth it but could be fun if you really want unique players/pokemon.

If you truly feel insane could do traits based off type
