Given your previous comments like this one and this one, it is clear that you have unrealistic expectations about tutorials. You seem to be discarding tutorials not because they are actually lacking depth, but simply because they don't have copy-and-paste solutions for your specific setup. That is no way to learn.
No amount of tutorials will cover everything you want to make, the same way no amount of chess manuals will cover every situation that can arise in a chess game. You have to learn how to adapt solutions and solve your own problems, and that is your responsibility. If you don't want that responsibility, get a different line of work.
