I have searched the documentation but am finding this still to be a bit ambiguous and unclear, especially with regards to the new Vars API.
What exactly are the new O: or I: vars, and what can be done with them? What are the “Components” that they affect/control? Any examples somewhere?

O: and I: vars are not really new, we have had them the whole time. They are used where you want a local scope variable. Like a lever needs to store its position and an O: var makes sure this is never confused with any other lever’s position var.
