Does anyone have advice on dealing with Blazor not being reactive out of the box?
assuming you're referring to the UI not updating when the state changes, the issues i've had with that were mostly resolved by ensuring all my UI event handlers were EventCallbacks, which automatically re-render components after the callback finishes

Puzzled about Nullability in EFCore
what i didn't include (but probably should have, sorry) was the definition of AB 
public class AB
{
  public int AId { get; set; }
  public int BId { get; set; }
  public A? A { get; set; }
  public B? B { get; set; }
}
public class AB
{
  public int AId { get; set; }
  public int BId { get; set; }
  public A? A { get; set; }
  public B? B { get; set; }
}

it's not going to be 100% analagous to your case because your case doesn't have two different entities being joined

not really, in your case A and B are just the same entity

the difference is that if you explicitly create a type and DbSet for it then you can query the join table directly and also add more columns on to it if you need to

EF doesn't care about required. If the property is a non-nullable guid, it'll be required in the database

I personally like to explicitly type my many to many relationships, so for me if A and B have a many-to-many relationship through the join table AB then I have 
class A
{
  public List<B> Bs { get; set; } = [];
}

class B
{
  public List<A> As { get; set; } = [];
}
class A
{
  public List<B> Bs { get; set; } = [];
}

class B
{
  public List<A> As { get; set; } = [];
}
and then configure them with HasMany(a => a.Bs).WithMany(b => b.As).UsingEntity<AB>() using the fluent api
