You missed a few things.

1. Platinum Travel Credit of $200. This brings the card down to $499 as a net cost. The Fine Hotels & Resorts rate can be more expensive at times, but the benefits of property credit, early check-in/late check-out, breakfast and room upgrade is quite useful. Vegas might not be the best place to use it. The travel website contains all types of hotels, not just the high-end ones... but what weekend did you go? I found the rates on Canada Day to be quite reasonable for higher end properties like the Bellagio, Mandarin Oriental, etc.
2. Cathay Pacific Marco Polo Gold. This benefit is ending at the end of the month, but since it seems like you've had it for a month, you should've gotten it before it ended. Cathay has some great lounges around the world, and the Gold membership allows you access into Oneworld (American Airlines in North America - AAdmirals lounges) lounges on any class of travel as long as you're flying with an Oneworld airline. This status also gives you priority check-in, boarding, etc. Lasts for one year and then you get fast track to maintain status.
3. Plaza Premium and Priority Pass lounges are found in most major airports. YVR, YYC, YEG, YYZ, etc, all have such lounges, as do most USA airports. There is a Priority Pass app that helps you find lounges worldwide, and Amex's website has a lounge finder.
4. Airline benefits can be useful for international travel, not so much for North American. The one useful thing for Canadian travel is the Platinum discount for Westjet fares.

I haven't used the concierge or car rental, so I don't have much to say in that regard.
