It took a couple of weeks but I finally made it all the way through this thread. That OP is some amazing stuff!

To contribute - I've seen Writing Excuses brought up a few times in the thread, but not Brandon Sanderson's main YouTube channel which contains all of his BYU lectures on writing SFF and some other miscellaneous questions on writing that he's been answering during his livestream signing sessions. This is the playlist for the 2020 lectures:

Most of what he covers applies to any genre (or any storytelling really), though there's a few that are very specific to SFF (e.g. world building and magic systems). He also has 2 lectures covering the business/publishing side of things (traditional and self publishing).
