USS - circles on the bumpers.
Heat pump, power trunk, heated wheel - my December 2020 (so 2021?) LR has heat pump and powered trunk, but the heated wheel came about 4 months later.
Premium audio - you're correct.
CCS adapter - don't care. Tesla has the world's best charging network, and with Ford's recent announcement that they're going to adopt Tesla's connector (NACS), there's a good chance that CCS will go away in the US.
There *are* some owners that appreciate third-party chargers... usually because they find a free one or because they travel in one of the few places where Tesla's superchargers are not as prevalent. Home is 99.9% of where my charging happens. On road trips, the in-car navigation gives you all of the charging stops, and they're all Tesla superchargers.
