i learned everything i know from video essays on youtube. there are so many of them, i'm sure something will interest you. here's a playlist, and you can find more from these good creators.

these types of videos will make you a better filmmaker, but maybe not really help you know how to start, like what camera lens to use or how to record sound. im sure there are videos like that, but im not knowledgable in that area.
studiobinder has a lot of videos about fundementals and terminology, like this one that explains camera movement, so you can learn all the names for techniques like pans, zooms, tilts, and like the difference between tracking shots and trucking shots

so i recommend just watching whatever interests you. watching video essays have massively increased my appreciation of films. like this one about the colorwork in Nightcrawler. i liked this movie before, but after i saw this, i was blown away by how many amazing details there are that i didnt even notice the first time i saw the movie. and now that ive learned all this, i can spot more details in every movie i watch.
