>But also sometimes it makes more sense to copy and paste over trying to fit an abstraction where it shouldn't be. :)

depends on goals. diverging modules should be copy-pasted, two modules that rely on the same functionality should be consolidated (not necessarily abstracted, but synchronized somehow). Those are both two common cases, so there's no general advice on which is better.

>Good intermediate (I suppose Sr. in our industry) level code is notoriously difficult to find examples of and mentor toward.

so much industry code and knowledge is proprietary, so I imagine that is by design. even intermediate code has a bunch of value to a company, even if the company lets go of that engineer to make their earnings report 0.1% higher.
