I quite understand your frustration. As a PPL with several hundred hours on light singles and twins and 15 hours in a sim (with TRE), I have enough understanding of line ops to know how little I know
It's a shame that pax don't have access to a "flying for dummies" type of guide, that would explain in simple terms things like what V1/Vr is and how runways are factored etc.
The guide could also explain why it's important to observe the seat belt sign etc and generally create a low level of airmanship that would help the cabin crew.
If there's an upside to your frustration, it must be that you and your airline colleagues are educating some of your pax, as irritating as the process can be at times
