What are the must-have accessories for a new Mitsubishi Outlander PHEV?

Okay so I just put a deposit down on a 2024 Outlander PHEV and I am literally freaking out because I have never even owned a hybrid before let alone something you plug in. I keep seeing people talk about all these extras and I have no clue what is actually necessary and what is just a waste of money. My budget for this is like 500 bucks max because the car was already way more than I expected to pay.

So I was thinking maybe I need weather mats because I live in Oregon and it rains constantly and I dont want to ruin the floors on week one. But then I saw someone mention a level 2 charger at home and now I am confused like do I need to buy a whole separate box for my garage or does it come with one that works? My logic was that the car comes with everything but then I read a forum post about must have charging cables and now I feel like I am missing a piece of the puzzle. Also should I get a screen protector for that big middle display thing? I have kids and they touch everything with sticky hands. I am taking this on a road trip to the coast next month and I am so scared I am gonna forget some cable or something and get stuck. Sorry if this is a total dummy question I just really dont want to mess this up...
