There are super cheap usb-a to usb-c-female adapters, tiny little cable-less adapters. I heartily recommend buying in quantity, so your existing charging gear can all expose usb-c.

Then I buy usb-c to usb-c cables. And a usbc-to-usb-micro adapter, which comes with a little chain that clips on to the cable. I use less and less micro (the majority of my recent dev boards have been usbc for example) but having a cable good for both is super convenient & easy.

I'd be careful with these: USB-A male to USB-C female adapters are illegal in the specification because they let you connect two power sources together, which can lead to explosions.
I'm pretty sure you can easily do that with a presumably legal USB-A male to USB-C male cable.

Plug one end into a charger with a USB-A port (very common among phone chargers) and the other end into a charger with a USB-C port (Apple's chargers seem to be like this?).

It's forbidden to make a charger like that unless it has a chip that actually speaks the protocol and does power negotiation properly. Same for anything that has a female USB-C port.

The trick is that USB-C has a pair of pins that identify what type of cable is connected. Different value resistors on the pins identify different types of cables, so the USB-C charger will know that the cable plugged into it is a legacy A to C cable, and not actually connect its VBUS.
