I had to do the same sort of thing with my MacBook Pro. Only two USB C ports. If you use one for the charger, that leaves one open port. Had to get an add on USB hub.
Like I said, the Macs are still good machines, but they used to be the go to machine for the creative. Now, they're more like jewelry.
The new MacPro is a great step but only for the people that can afford expensive jewelry. I still have three old Mac Pros that I now use just for the Web Browser and do little else, too old to care anymore. My eyesight is so poor that I use a 70 inch 4k TV as a monitor and spend a lot of time on YouTube seeing the wonders of the world. I would rather watch a prepper wrestle a log onto a home made sawmill than watch the next "bombshell" story on the news.
