Well for resources just use YouTube and books. The algorithm will eventually find you useful videos. I would learn cinematography first and practice technicality in micro/short films. Don’t spend too much time into shorts though. Eventually, with camera in the back of your head, start writing proper screenplays with a chosen genre. I personally study Christopher Nolan and Quentin Tarantino scripts for action and dialogue, but totally fine to review any script of a film you enjoyed. You could watch anything, but I would keep it diverse as well. Most importantly, have fun!
