After spending my career watching high priced consultants come in to give us their ‘expert’ advice, I concluded that the definition of ‘expert’ is anyone who traveled more than 50 miles from their office. And, since I am traveling right now, I guess I would qualify. However, since I don’t use conFusion360, I won’t claim any expertise in that domain.
SheetCam is easy. You don’t need to do anything special with your design. SheetCam will use the exact center of the hole if you use a Drill operation. Do a short pierce burst and it will leave a nice centerpunch where you want the hole. As @jamesdhatch said, the details are posted. Useful search term would include ‘small holes’ and ‘peck’.
