does Advanced Record constructor automatically zero all the memory
space of that record?
No, it does not. Neither in Delphi nor in FPC.

if not, is there a clean and easy way to initialize the entire record

constructor TMyRecord.Create(TheValue : Integer);
begin
FillChar(self, sizeof(Self), 0);
Value := TheVal;
end;
You can use either FillChar as you did or use "Self := Default(TTest);"
(default is a compiler intrinsics that returns a 0 value of the type you
passed in, e.g. Nil for classes, '' for strings, 0 for ordinals and for
records all fields are set to 0)
Is there a Self variable for advanced record methods/constructors ?
Yes.
By the way, is there an ultimate inherited constructor "Create" for
all advanced record types?
No.
