I'm having a bit of trouble understanding variable differences. I understand Int is a number, String is text and gameobject effects the gameobject but WHEN to use them or events is always confusing and feels like guess work. Is there any person who can do a one or two sentence explanation of what each variable (or global events) is best utilized being used for?

I'll try to beef up the docs for this. But in the meantime, here's a quick summary:
Variable Types:
- String - Text
- Int - Integer or whole number (1,2,3...)
- Float - Floating point number (0.5, 1.2...)
- Bool - True or False. Useful to store the results of a test.
- Vector3 - Three Floats: x, y, and z. Typically used to store position or rotation.
- GameObject - A reference to a GameObject in the scene/project.
- Rect - Defines a rectangle using four floats: x, y, width, height.
- Material - Stores a reference to a Material in the project.
- Texture - Stores a reference to a Texture in the project.
- Color - Stores a color.
- Quaternion - An advanced representation of a rotation. Sometimes actions will use this for better interpolation between 2 rotations.
- Object - Any type of UnityEngine.Object. This lets you reference all sorts of properties in Unity. It's also pretty advanced. We'll make some tutorials for this soon.
TIP: Rollover a parameter in an Action to see its Type. This will tell you what type of variable to make.
Global Events: If you want to send events between FSMs they must be marked Global.
Global Variables: If you want to easily access a variable from any FSM, make a global variable (e.g., NumberOfLives, Score, PlayerName...)
Hope this helps some!

While helpful, I think beefier explanations into the documents would be most appreciated <3
