Find a local teacher. Some lessons will make a big difference early on. Perhaps you local music shop if they recommend someone?
Online is a great resource, but doesn’t replace in person. Perhaps Marty Schwartz, he has tons of youtube videos with various songs you may like.

If you totally want to nerd out on Rock music and it’s composition,
Rick Beato.
