Timeline:
08/09/21: Applied at post-office in Houston (They ship via priority 2 day by default)
08/11/21: Probable delivery date quoted by the USPS staff at submission (they do not give you tracking number if you apply at the Post office)
08/12/21: Status changed to "In Process"
08/13/21 (Friday): Reached out to my congresswoman's office as I needed to travel urgently. I faxed the privacy form (usually most of them have it on their website) before getting the acknowledgement.
08/16/21 (Monday): Received email that congresswoman's office had placed an expedite request
08/17/21: Passport and Passport Card shipped via overnight UPS. Expected delivery date (on UPS website): 08/18/21

Total time, door to door: 8 business days.

Contact your reps promptly if you need the passport urgently. It works.
