What are the must-have interior accessories for a Ferrari 296 GTB?

So I finally got my 296 GTB delivered to my house in Coral Gables after waiting like a year and a half and honestly im more stressed out than happy right now. I know that sounds stupid but this is my first real car and I have no idea what im doing. When the guy dropped it off he just showed me how to start it and left and now im sitting in the garage looking at all this leather and carbon fiber thinking i am gonna ruin this in like two days. I tried looking up what people buy for these cars but everything is so complicated and half the websites look like scams or they use words I dont understand. Like what is a frunk liner and do I actually need one??

I went to get coffee this morning and I realized there isnt really a good place for my phone that doesnt feel like it's gonna scratch the finish and im terrified of the floor mats getting dirty. My shoes had a bit of sand on them and I almost had a panic attack. I feel like an idiot for asking this because obviously if you buy a Ferrari you should know this stuff but I really dont. I just want the interior to stay looking new but I also want to actually drive the thing without feeling like im in a museum. Is there like a kit or something? Or specific brands that people who actually know cars use?

I have some money set aside for extras maybe like five thousand bucks but I dont even know if that is too much or not enough for basic stuff. I keep seeing people talk about screen protectors for the dash which sounds crazy but maybe it isnt? I just want to know what are the absolute must have interior accessories for a 296 GTB because I am totally lost and the manual is like five hundred pages of stuff I dont understand. What do you guys actually put in your cars to keep them nice...
