I use a single hub for everything but video, for which I use a USB-C -> DisplayPort adaptor that supports 4K@60Hz. It’s a minor sacrifice to contribute to the normalization of a new, universal port standard that is orders of magnitude better than the old standard.

If they had retained just one USB-A on the MBP I would be so much happier with mine.

That said, even with just USB-C the dongle situation is still complicated— the plug form factor may be universal but the signals aren't. IIRC Apple's own Thunderbolt dongle doesn't actually work with Displayport signals

I agree it's a much better standard, but it's not a minor sacrifice for every one. There are a lot of old things which will be discarded and contribute to e-waste, though that may be somewhat offset by one connector. I wish people didn't go quite so scorched-earth on one port, especially apple. Just offer both for a while.
