That fair, truth be told.
Vampire Spawn, by proper realms lore, aren't even really fully sapient creatures at all; they are quite literally soulless empty creatures with no will of their own and no sense of feelings or emotions - they are capable of acting like they do, but it is 100% an act. If you want a sapient undead, a spawn is not the answer.
Vampires working with werewolves is straight out of old Dracula lore, which has nothing whatsoever to do with the forgotten realms - but again, Larian mostly took the idea that h"they know what vampires and werewolves are, right?" and did their own thing, seemingly without caring that, in the forgotten realms, those things have certain rules and are defined a certain way, and not other ways (we've already covered how staking Astarion while he's creeping on you would have done little more than ruin his shirt; it would not have had any effect on him whatsoever, because that's not how vampires or their spawn work in the realms; Larian do not care).
Lycanthropes come in a variety of alignments across the spectrum, but this is generally dictated by the strain of lycanthropy they have; what are strong natural impulses and inclinations are further leaned into and heightened by the types of social structures (or lack thereof) that various types of lycanthropes tend to form or gravitate towards. Werewolves are almost always independent and fiercely Chaotic Evil (though in the wild, I think they do tend towards forming packs around themselves of wolves and dire wolves), while weretigers are generally neutral, and werebears most commonly form neutral good societies, as a few examples.
Edit: Piff beat me to it - her information is accurate to current 5e.
