Applying for non-faculty jobs - advice?

Every field is guilty of some form of navel gazing. Hence the abundance on how to apply for faculty jobs. Margaret Kosmala wrote a recentish blog post on this, with some advice I agree with, but also some I do not agree with. For instance, often departments fight over every single word in a job ad, so showing that you understand the needs that will be filled by the position (i.e., your contributions to the department and university) are important.
However, given one of my previous posts (see here), if only 10 percent of our graduate students end up in a faculty position, what resources, blog posts, advice, etc are out there for graduate students ready to make the transition?
