Inheritance and Script References c#

Hi, I want to know how I would structure the following example.

I have an "Actor" script which inherits from mono behavior. I then have a "Player" script that inherits from Actor and an "Enemy" script that also inherits from actor.

If I add the player script onto my player game object does this create an instance of the player class? If so how can I get a hold of a reference to that object instance. I need to be able to have a variable in the Player class that is a reference to the targeted enemy. So that information from the enemy can be passed to the user interface and/or other functions. However when I try the following:

 Enemy target;
 
 void start()
 {
     target = GameObject.Find("Enemy").GetComponent(Enemy);
 }

Surely this gets the script component (Enemy) of the game object "Enemy"?

I currently have a game object with my player script attached and an empty game object called "Enemy" with the Enemy script attached.
