The variety of ways you can achieve your desired results is truly amazing.
I also found Bruce Williams' tutorials very helpful

Yes absolutely; his channel is great. I'd also recommend watching Aurelien Pierre's elaborate introduction to Filmic. He's the main developer of that module and one of the core developers of Darktable.
A lot of thought went into the last few releases and it shows.
