Honestly the 3M 60923 cartridges don't restrict breathing at all. They have great airflow. I've used them all day long in chemical plants, no one complains about that.

I usually put those in a parts drawer for use when opening electronic devices built with clipped together plastic cases.
Good tip, though! I'll have to try that next time I'm using the bayonets.
Seconded. I've used those exact cartridges. Not for as long of shifts as you, but I'd say the face mask fit is much more important for that.
My DIY-perspective tip is that when you're getting to know the respirator, you can take the filter cartridges off and put your hands over the input ports to feel what fully restricted breathing feels like, make it a known sensation in case it ends up happening. Likewise you can cover the output port and breathe out to do a kind of rough fit test.
