*BBM released a set called Glory after Fusion was released, but it has a 2021 "issue year" so it doesn't count.
There are several inserts to be found in the set. The first two are found at the same rate as regular cards.
The next two sets are standard BBM inserts, found at a lower rate than the base cards.
There are two premium insert sets, Phantom (#/25, 12 cards, one per team) and Esperanza (#/50, 24 cards, two per team).
As for autographs, regular autographs can be found for many subjects #/10-90. The cross-set Cross Sign Autographs feature 16 cards using the Cross Blossoms design, serial numbered between 10 and 30 copies each. Finally, nine First Pitch Autographs can be found #/25-55 copies, with a special Foil version #/5.
