Finally bit the bullet yesterday after I encountered some annoyances with my iPhone 11 Pro over my trip (mainly waning battery endurance -- 86% battery health will do that), so I ordered an iPhone 15 Pro and have already started ordering accessories, such as Thunderbolt 4 and USB-A>USB-C cables for my cars and so on.
For the cars in particular, picked up a pair of these bad-boys:

According to reviews, they work for Apple CarPlay and Android Auto, which basically future-proofs the cable and the infotainment upgrades I've done / will be doing. Great if you have a co-pilot who wants to use their phone for CarPlay / AA, or if you sell the vehicle down the line.
Also picked up new JETech tempered glass screen protectors and a very nice looking leather case for it.
