Most things I have and still use, use usbc for charging or power. Or lightning.

Peripherals, usb-a is still what you usually get, just going by what’s common on store shelves. Just got a new kit at work a few weeks ago—all these brand-new devices are made to plug into A, even if the other end is usb-c. They come with A-to-c cables, or else are A-only. In the former case, I can at least fix it by just using c cables I already have.

But, overall, the peripheral world as most people experience it is still A-first. C options are usually more expensive, may be part of why.
