The closest you got to CEL was a pending P0300. That's multiple random misfires, but not enough events or persistence to trigger a CEL. No isolation to bank 1 or bank 2.
My car has always had intermittent misfires when cold, particularly during the first minute after startup. Never got a CEL. I just take it easy like I do with all engines until I get some heat into them.

This is pretty much every morning for me!
