Next time, please organize what you are trying to ask.

In short:

1. I-20 applies to your student visa only. So if you are not using your student visa, no one really cares your status at SEVP.

In your case, you will only have a problem if you have another I-20.

2. Travelers tend to have worse experience in Vancouver Preclearance. In other word, you are picking a more difficult route instead of an easy one.

3. In your case, using VWP with ESTA will be a risk as you just leave the U.S. with a student visa. You pose a risk of intention to stay.
