What are the must-have accessories for a new Chrysler Pacifica PHEV?

I just picked up my 2024 Pacifica PHEV yesterday and honestly I am so overwhelmed with everything. Like I didnt even know what a Level 2 charger was until the guy at the dealership mentioned it and now I'm worried I'm missing a bunch of stuff I actually need. This is my first ever hybrid or electric car and my first minivan too so its a lot of firsts all at once. We are based in Seattle and it is already starting to get really muddy and rainy here so keeping the interior nice for more than a week feels like an impossible task especially with a 3 year old and a 6 year old who basically live to spill juice boxes and track in dirt.

I have about $700 or $800 left in my car fund to spend on whatever accessories are considered essential but I have no clue where to start or what brands are actually good vs just cheap junk on some random website. Sorry if these are really basic questions but I just want to make sure the car lasts and I dont mess anything up with the battery part of it.

Here is what I think I might need but please tell me if I am wrong or if there are better ideas:

• Something heavy duty to protect the floors from all the mud and crushed goldfish crackers
• Do I need a special cable or something for home charging or is the one it came with okay for now because the garage outlet looks like a normal one
• Is there a way to organize the huge gap between the front seats? It feels like stuff just rolls around there whenever I turn a corner
• Screen protectors? I saw some online but I dont know if they actually fit the big dashboard screen
• Something to protect the back of the seats from little kids feet kicking them constantly

I really want to keep this van in good shape because it cost us a fortune and I want it to be our main family car for the next ten years at least. If you guys have any must haves that made your life easier with the hybrid battery or just the minivan life in general please let me know because I am kind of lost...
