The Mitsubishi Evo and Subaru WRX probably have the most hacked ECUs around. Loading something like ECUTek onto a BRZ or FR-S gives you equal control. Convenience systems are usually controlled with some kind of aftermarket device, though for Toyotas, you can download Techstream and control a few options via a cheap cable off ebay. A Tesla offers the most toys to play with out of the box, but you can't do a think with the actual drive system. An M-series BMW like an old M5 will give you loads of setting
Unfortunately, most of the stuff mention in the OP aren't controlled by the ECU. Windows, lights, starter, really anything other than the engine aren't controlled by the ECU. The climate system is wired to it, but only so that the ECU can adjust the radiator fans to handle A/C load.
BTW, I'm certain of this because I just used the ECU/engine from a WRX to build a custom car.
