For example, if I define a Subscription Schedule for a Price with interval=month and interval_count=1 and set iterations=12 on the Schedule.. Will it automatically progress out of the phase and into the end_behavior after 12 months if we only collected 11 successful payments?

end_behavior happens regardless of if the final payment is received or not

Is there any possible way to express "I want this Subscription to be charged X times on Y interval and then canceled after X successful charges?"

Unfortunately not. You would need to write some custom code that checks the payment status of the final Invoice and then performs the action to either cancel or not cancel.
