I say choice 1 or 3, whichever is in better cond. You are only planning on keeping the car for 3 years and plan on having under 100k miles. All of them should be under the extended manufacturers warranty for at least 2 of those years as you don't plan on going over the allowed mileage, right? If you were going to keep the car for a long time, I would say pick the one with the lowest miles, but in your case the milage really doesn't matter that much as they are all fairly low.

Forget that extended maintenance plan and just take the car to an indy shop if you are not planning on keeping it for more than 3 years or 85k.

The CPO extended manufacturers warranty (which you get purchasing CPO) is the important of the 2 warranties. If you really want to buy the maintenance plan, check to see if the brakes were changed on any of the X's you are looking at. That will be your biggest cost that the maintenance plan will cover. As I said before, you can get oil changes for under $100 and you will need 3 according to the mileage you plan on driving and when you plan on selling the car. So there is $300. You can change the brakes yourself for about $450. So there is $750. That is much cheaper than the maintenance plan. Even if you can't change the brakes yourself, you can go to an indy shop and get it done for much cheaper than the dealer adn the overall cost of 3 indy oil changes and 1 indy brake job would still be less than buying the maintenance warranty. Your call though.
