Congratulations! There are multiple different videos on YouTube that will give you reviews of everything. It seems a basic consensus is a screen protector, all weather mats for the floor, trunk and frunk (depending on where you live and what you plan on putting in the trunk and frunk), if you have children in car seats possibly a seat belt extender because the seatbelt fasteners are flush with the seat and hard to clip in, especially for little ones and you also would want a car seat mat. Probably some cup holder inserts (for some reason they don't stabilize drinks), mud flaps, console organizers, and a hub to increase your ability to charge stuff in your car.
You also may want to think about protecting the car itself and get some paint protection film, but these can be expensive especially if you have a shop do it.
Enjoy your MY, I am still waiting for mine....
