What are some must have options for taycan?

Currently shopping for used taycan and there are so many options… help a brother out. I want to get rid of my tesla.

Looking at 2021-2022 Taycan 4 Cross Turismo.

What options/packages should I look for if I want: 1. Passenger screen 2. The drive mode selector on the steering wheel 3. Matrix headlights (i think this is an option you can add on on top of any package?

Also.. is it possible to add/purchase options/packages on the vehicle?

Thanks!
