One of the voice actors was in his element, at least.
July 17 - Theodora
Weapon and movement type: Shown as a lance infantry, but that could be based on Three House's "Soldier" class which had access to axes as well.
Bow down: The only explicitly confirmed royal so far: getting some "Queen of Solm" vibes, especially since her battle demo video has her using a battalion.
English voice actor: Shara Kirby
Prior VA Fire Emblem roles: Heroes-original character Ganglot.
Other Nintendo roles: Bea in Pokemon MastersEX and Deborah (+ a sage) in Unicorn Overlord.
July 21 - Bonaventure
Weapon and movement type: Black mage infantry.
By way of explanation: Black mages use spells like Wind and Thunder, dark mages use spells with names like "Miasma" and "Death".
English voice actor: Dave Fennoy
Prior VA Fire Emblem roles: None
Other Nintendo roles: Voiced Rodin (bartender/weapon seller) for the entire run of the Bayonetta trilogy.
