I feel the same as you guys...tech and torque. I've been doing things incrementally to upgrade performance. I bought a used Accessport, which comes with free Cobb tunes, and using stage 1 tune right now. I finally ordered an intercooler a few days ago so I can run stage 2 in a couple of weeks. Next step will be talking to goosetuned when I get tired of the cobb stage 2. The intercooler is definitely the most expensive part so it's nice to spread it out.
For the screen you could always go with an aftermarket "tesla" style screen. I had a similar android setup on my 2012 X5M and, while the android side was kinda crappy, it improved the resolution and size of the stock idrive screen. I don't think there are any screens for the F150 that keep the sync3 though and none of them have stood out to me.
For wireless Apple Carplay in the Raptor I use the Carplay2air adapter. The adapter has worked flawlessly with no drop or issues. The only downside to it is a 15sec loading screen while it connects at startup and the fact that the loading screen looks like a cheap Chinese interface. Otherwise, it autoconnects to your phone and even autoresumes music.
