It looks like others have already responded to most of your points, but I would just add:

If you just "need to get stuff done, not tinker", then you should not upgrade to a new OS immediately after it is released; wait a month or two. It is inevitable that a new OS release will break some ports, and it will take time for the maintainers of those ports to notice those problems and figure out the solutions, possibly needing to work with the developers of the software to release a new version. 

Regarding updating pandoc, see https://trac.macports.org/ticket/48324

Regarding updating ghc, see https://trac.macports.org/ticket/48899

Regarding old llvm on Sierra, see https://trac.macports.org/ticket/52424
