From all the shutter modes available in the Canon R6 Mark I, the one that I always use is the Electronic First Curtain Shutter or EFCS. In the Canon R7, I was using Electronic Shutter most of the time, but I stopped using it in the R6 because this camera is totally silent in this mode, and I love to have the sound feedback from the shutter.
Here is a nice video explaining the differences between the Electronic, Mechanical, and EFCS.
