I’d like for someone to tell me the pros (and cons) for using the post function. Why and when should I prefer using post and why/when should I not want to use it?

Post is very useful when you want the callback to occur essentially now, but not in the current context. Reasons might include:
The current context is holding locks and you want the function to be called after they have been released. This would allow the function to acquire those locks itself without causing a deadlock.
The call stack might be very deep
The current thread might be inappropriate for the function in some other way, and post is a convenient way of scheduling the function in another thread.
