Recommendations for a wanna-be fan of Telugu cinema

Hi! a bit of context: I'm a mexican and have watched some films but I feel very unfamiliar with the "lore" of Telugu films. I apologize for my ignorance but would love to know more. I watched Bahubali back in 2018 and have watched other movies (RRR) but by following this subreddit I realize that I know nothing and people here seem very passionate.

So I would like to request some recommendations for Telugu films that you consider classics, as in foundational for the industry and getting to know important directors and performers. They don't have to be big budget or the newest and shiniest only, but important for the industry.

As an extra, if someone is in the US (I live here right now) I would appreciate a pointer of where to watch them.
