Based on a list I found in 2017 that also includes the various DCAU comic series too. Those won't be on here, though.
The following series/movies are not canon and should be skipped if desiring a purely canon DCAU experience:
Batman: Mystery of the Batwoman
Superman: Brainiac Attacks
Batman and Harley Quinn
Justice League vs. The Fatal Five
Teen Titans (whole series)
Young Justice (whole series)
Legion of Superheroes (whole series)
