Look here for the parts info and some other details about doing the donut spare. Use Invoice Part # for dealer purchase. For a less expensive option a compact spare, jack, wrench and assembly box from a 2013+ gas Fusion should work. The hold-down bolt for the mobility kit is reused for the compact spare hold-down.
Size: This sets you up with a 16" compact spare that will fit into the well under the floor. Swap it for the mobility kit. For 17" usage this doesn't affect things too badly when it's used but with 18" setups there a little difference. Use the compact spare on the rear when using 18" rims ... otherwise your steering will be very out of true and that's not good. Ie., for front flat, use a rim from the rear on the front flat side, then the donut on the rear position.
Weight: The compact spare and gear are about 30-35 pounds, so this will affect MPG if that's a concern for you.
Personal: I put the compact in my prior '15 and then the current SE. I kept the mobility kit in the garage and simply swapped it in when needed. I went the dealer route because salvage yards around here want almost as much as I paid at the dealer. Oh well.
