This fundamentally depends on the people and dm you are playing with. The group I play with has decided that common enemies your players would know how to deal with weaknesses etc. Just like a person from Australia knows which spiders are poisonous or not.
Uncommon enemies you know you have to pry for weaknesses. We also play shadow dark so character longevity depends on the experience gained from previous encounters and PC deaths.
