I asked @theacodes on here this same question, on a post they'd written that like.. actually got into "ok, I'm putting this capacitor here, because it's gonna do <x> for me, another way I could do the same thing is..", and their reply is here: https://news.ycombinator.com/item?id=33484848
I do think there'd be a lot of value in blog or youtube series of experienced circuit designers showing how they approach things, why and how they pick components etc, it's a great way to learn. The blog post that HN thread is about is really good as an example.
I've had several people recommend "The Art of Electronics" as a reference for circuits building as well, but haven't read it yet
