A is a terminal plug. The switch from A to C you swap cables. They sell micro and mini cables with C terminals. A few devices come with A terminals hard wired still, occasional mice and keyboard. But most high end devices don’t have hard wired cables, they come with complementary cables you can easily swap out. I swapped to usb-c everywhere a few years ago without swapping my devices - just cables - and use zero adapters. I still have a few just in case but it’s increasingly unnecessary to listen to Nirvana while plugging my devices in.
