I picked up this Startech USB-C dock: dual Displayport, USB 3.0, Gigabit Ethernet, and 100W power delivery (way more than the PBP needs, of course, but powers my partner's high-end Dell machine with ease)
https://www.amazon.com/gp/product/B07JZHVKFJ/
I'm running the default Debian install (updated) on my PBP, and I have two basic VGA 22" widescreen 1080p monitors connected via simple DP > VGA cables.
I can't verify that the ethernet or usb 3.0 works as I haven't used either of those yet, but I can say that it charges and displays on both monitors just fine. However, the two monitors act as one secondary monitor (they are mirrored) with the PBP screen as primary. Not sure at this point if it's a limitation on the PBP's ability to drive three 1080p monitors, compatibility with the dock (it is billed as Mac/Windows, but that never explicitly means it won't work with Linux), or if moving to Ubuntu-Mate will help (as seems to help with a variety of things).
