I would like to know how to create a variable that points to the same data as another variable, capturing its value automatically.
For example:
var a = 1
var b = mirror of a
a = 2
print(a) # 2
print(b) # 2
I know this applies to objects like Dictionary, but I would like to know about other data types.
I cannot think of any data type that does this, but you could create a function that updates two variables to have the same value. Would this work for you?

To expand on this comment:
extends Node2D
var a: int = 0 setget set_a, get_a
var b: int = a setget , get_b
func set_a(value: int):
a = value
b = a
func get_a():
return a
func get_b():
return b
Just always go through the setters/getters for the variables.

I’m pretty sure stuff does not work like that in GdScript for simple data types. Because what you want to do is have a pointer to your value instead of having it saved. In C++ you it would be straight forward, on the other hand, in GdScript, all that is handled by the interpreter and you can’t simply do it.
As a work around, you can create a class that holds a value, your int for example and use instances the class to access the values. This works because any instance of a class is a complex object, thus accessed by reference.
