In the North American court system, a defendant is presumed innocent until proven guilty – – that means the court system’s null hypothesis is what?

In an ideal (Just) world, the truly innocent will always go free, and the truly guilty will always be convicted. Type I (incorrect rejection of null) and Type II (incorrect retention of null) errors could occur in the legal system. If that is the case, what are the court system equivalents of Type I and II errors?
Purely in terms of outcomes, which one would the defendant prefer?
which one would the prosecuting attorney prefer?
