Interesting questions, Judd. Back in the day, even in a company wth quite rigid, but not intrusive SOP's, I flew with various old dogs whose takeoff brief was the flap, the thrust, SID, the emergency routing and "the rest will be SOP's". The same with an ILS or visual approach. The approach brief was "SOP's + salient items for that particular day."
Too much Blah Blah, that is just repeating of SOP's causes boredom and switching off. It's like the wife telling me how to fill the dishwasher. The second thing with too many callouts is that under stress the first thing that shuts down is your ears; thus yapping too much has the opposite effect of 'trying to be helpful'. You gave up listening long ago.
