Your advice seems to take a different approach -- that you shouldn't use questions as a means to ensure you will be happy in the job, but rather as yet another opportunity for status signalling.
Even the first sentence depicts a totally alien attitude to me: "questions that really hit home with the employer are..." ... What? I have no obligation to ask questions that "hit home" with the employer. If the employer doesn't like the questions I do ask, well that right there is a good indication that I would be miserable working for them and should just work elsewhere.
By approaching even the part of the interview where you get to steer the topics of discussion (your questions) with an attitude of infinite pliability and fealty, it makes the process even more about subjugation and hoop-jumping than it already is.
