CAUTION - TURNAROUND
"One customer did have issues. Wang Guanran, who documents his travels on hktravelblog.com, had his plans to travel to New York on Wednesday cut short when he was prevented from flying by immigration officials in Vietnam... he was detained by Vietnamese immigration officials, who said it was illegal to return to his city of origin while in transit." - Source:SCMP, 2 January 2019

Visa Information: check out the Vietnam visa/VOA thread in the Asia forum. You can get either a visa on arrival where you get the stamp on arrival) or a "looseleaf" visa in advance from a VN Consulate in the US (which allows you to go straight to the immigration queue). There are sometimes lines for the VOA stamp and so the loosleaf approach can save you some time.
Seat Assignments
per NWPlatinum below - Cathay blocks out all seats except for 2D for some reason. I never understood the reasoning behind this but in any event just contact them for a seat assignment and they’ll let you have your choice. They like to block out seats for people with bassinets and babies. But you can usually get 2A, which is the best see if you’re solo traveler. Just say I want seat 2A and I’ll move if requested at the airport (never was asked to move)
Basic Visa Options for US Citizens
1. One month, one entry
2. One month, multiple entries
3. Three months, one entry
4. Three months, multiple entries
5. One year, multiple entries
Everyone needs an e-visa approval before boarding if they will enter the country. (e.g. clear customs). Connecting flights - even on separate tickets - do not require a visa IF IF IF the connecting airline has a counter in the transit area. (The airline may have their own rules.) Going back to the same country is not allowed without clearing customs first.
Expect the visa check at your point of departure. (Computer will flag your ticket.) The actual stamp is received on arrival (in most cases). (There is also the possibility of a visa insert with no need to go to 'visa on arrival'.)

Tried to send e-receipt from CX site with ticket # from Expedia, but it's showing:
The e-ticket number you entered is invalid, please check and try again. [E23Z00100]
Is anyone else able to send a confirmation from the CX site?
Edit: never mind, it was an issue with Expedia transposing the ticket numbers for different pax.

WOW...
Just booked and ticketed DAD-JFK RT in FC for US$845. CX website shows it and selected seats. Hoping it's honored. Wow, thanks OP for sharing.

If so, it seems that seats are not selectable if you're flying all the way through to JFK and...
1) someone books a seat on YVR-JFK only --> this seat becomes unavailable for you
2) someone books a seat on HKG-YVR only --> this seat also becomes unavailable for you
In your case, seats 1A, 1D could be in situation 1, and 2A, 2D could be in situation 2, but although there are technically 2 seats, they're all blocked for your itinerary.
So effectively only seats that are available for the entire trip seems to be selectable in advance.
