ASP.NET Core Identity vs. Active Directory

I am writing a simple boring ASP .NET Core 6 app. Basically put info in the database, show info from the database.

So for managing users, what's the trade-off between using ASP.NET Core Identity and Active Directory? As best as I can tell Core Identity is easier to use while Active Directory supports more MFA approaches and it can connect to an existing AD server as a friend(?) and allow those users in (might find that useful).

Is there anything else to this tradeoff?
