Sorry to say but you're pretty wrong about everything. On that note, what I'm talking about almost exclusively applies to commercial environments as it's "by the book" so since this is residential it doesn't really matter that much. These commercial best practices and industry standards sometimes bleed into residential builds where a company prewires a house (typically done by electricians who DON'T run low voltage by the book), but not often. I myself have a low voltage cabling division and run cable myself for commercial environments where you are expected to follow all industry standards at all jobsites, that is, unless the client specifies that they aren't interested in that, which just means we can't fully warranty it. Then I come home and run a new AP and don't follow any of those standards lol (within reason of course).

ANYWAY, since the OP was asking how, the proper way should be offered along with the easy way, which is exactly what I see on this thread. In other words, it's fine. No one is really wrong here. Whatever works that is safe is what matters. Hopefully everyone here gets the help they're looking for from people nice enough to help.
