I believe the 36 is the biggest 12s road cassette SRAM makes and the road RD isn’t compatible with the larger offroad cassettes (which all all 1x only). Maybe there is an aftermarket road cassette option larger than 36. Obviously unsupported territory once you go bigger/aftermarket, but maybe an option. Also, if coming from shimano, keep in mind that SRAM 12s has a bit different philosophy on gearing. You’ll have a 10 tooth cog in the back and options for smaller front chainrings. So, even though your biggest cog in the back is a 36, you can have a 33 front ring to pair it with.
On the usb-c, I recently got one of their battery chargers (the one that charges 4 at once) and it was USB-C. All the previous chargers I’ve gotten from them were the old syle mini usb (including one from a new bike in 2024). The charger is the only thing that requires a cord that I can think of.
