Yeah, you’ve gotta do it all or you will forever be chasing rattles. I recommend laying CCF down on the b and c pillars. Vibration dampener and CCF on the floor. While you have the b and c pillars out, pull the headliner down on the front and rear. The front will give you access to the overhead console to add some CCF there, the rear will give you access to a large flat portion of the roof behind the sun roof to add vibration dampening. You can also check for 3rd brake light leaks while you are in there. Lastly, any panel that has clips and is plastic to plastic can be a source of noise. All the center console trim, a/c vents, etc can easily be popped off and a small layer of Tessa tape will solve all you problem, just like the door panel switches.
