Finding the right ballpark of grind size

I would like to hear from other DF54 owners some of your grind size settings to get a hang of what is the approximate setting for cold brew, drip, Aeropress, moka and espresso that you are using. This is my first grinder ever and I am not very familiar with how the different brew methods should look like powderwise. I know it depends on bean and tools used, but something like Aeropress between 40 and 55 would be good enough. Thanks.
