I just got to thinking... by "interface to the car itself" did you mean stuff like Bluetooth phone, steering wheel buttons, and backup cameras or is it more in-depth stuff like car settings and monitoring? I know the phone calls, steering wheel buttons, and backup cameras can be tied to aftermarket stereos. I'm not sure if they have figured out anything more yet or not.

I found this that supposedly fits your car and does wireless CarPlay, but unfortunately the cost and interface with the car itself is still going to be a problem. I do wish modern cars left the car interface, A/C controls, and stereo separate. This along with privacy concerns and reluctance to spend on a new car is what keeps me driving very old stuff.

It may not be possible with a car that new depending on if the stereo does other things than just audio, but you may want to consider an aftermarket Pioneer, Kenwood, etc. Our car is so old that it's stereo did nothing but audio so replacing it was easy, but yours might be more difficult. You could always check with a car stereo shop and see if it is possible with your car.
I'll second the Framework. I've had one since the 1st gen Framework 13 and love it.
I'm not sure if it will suit your needs, but I love Eqonomize!. I can use it from any of my computers by putting its data file on my NAS.

I'll second Mint as well. I play mostly small indie games but have played Cyberpunk 2077, Far Cry 5, and Terminator: Resistance with no problems. The worst I've experienced is having to tell Steam to use a different version of Proton for some games (I recently had trouble launching Cyberpunk on Proton Experimental so I downgraded to the next most recent and it worked fine). I also have an AMD GPU so no driver mess.
I only subscribe so I can follow channels I like.
Sometimes you gotta weigh job security and a tolerable work environment into the mix. Working for Musk doesn't seem low-stress.
I'm aware of what CarPlay is. I use it in my aftermarket car stereo.
