A trial by jury is guaranteed in every case except those dealing with what?

The right to trial by jury in a criminal case resides in both Article III, Section 2 of the federal Constitution (“The Trial of all Crimes, except in Cases of Impeachment, shall be by Jury”) and the Sixth Amendment (“In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury”). But the right isn’t as broad as those texts might suggest, meaning that many defendants have to settle for judge trials, where the court decides whether the defendant is guilty.
