My personal thoughts are that you should work with automatic settings until you get a few maps completed and get some experience with the drone and software. My first maps were done this way and were quite good. My procedure is obviously more complicated and I have found that, as you gain experience and become more comfortable with the basic flight procedures then you will be able to concentrate on more advanced settings.
The biggest two things you can do to get consistent results is to fly higher than you are tempted too (at least 175’ and 250 or so is even better - you even get surprising detail at 350) and to avoid including big expanses of treetops or other homogenous vegetation. I set my geofence to exclude expansive wooded areas where I can.
