I travel a lot and "having everything USB C" didn't help.
I had:
- a USB C cord that only supports power but up to 100W
- a USB C cord that supports power up to 60W and data at USB2 speeds. But didn't work with my USB C powered portable display. Because it didn't support video.
- a USB C cord that only supported power up to 60W and data and video.
I'm usually traveling with:
- My MacBook Pro 16 inch (USB C)
- Mouse/Keyboard (lightning)
- iPad Air 3rd Gen (lightning)
- iPhone 12 (lightning)
- AirPods Pro (lightning)
- Beats Flex (they hang around my neck and I don't have to worry about them falling out on the plane if I dose off) USB C
- a four in one wireless charger that I sit by my bed at the hotel. (USB C).
- a Anker battery pack (USB-C)
- portable monitor (USB C)
- Watch - weird Apple proprietary wireless charging.
But now I only travel with these cords for most of my devices:
Female USB A/USB C on one end and USB C/lightning on the other end. They support data up to 480Mbps and power up to 60W. They are $13.00. They are cheap and not too thick.

But for a truly "universal cable", I have three of these:
- Female USB A/USB C on one end
- lightning, USB C, and Micro USB on the other end
- 10GBps data transfer
- supports video over USB C
- Supports charging up to 100W.

They are like $35 and are much thicker and a little unwieldy and I don't need them just for charging anything but my computer and connecting my secondary display.
BTW, this is my portable USB Monitor

I can't use my iPad as a second monitor using the native ability in MacOs because of corporate software. I found out later that I could use Duet.
