One question I have, and I apologize if you answered this but I either don't see it or I missed it, but I know you said any race in DnD5e is available, if we are using DnDBeyond to create our character, what books are available for use? Only the corebook?

All official content. No homebrew. That's virtually every book afaik. Also every official class/subclass. That does mean no Critical Role classes (Gunslinger + Blood Hunter).
