Not in my experience. The last few times I went to try to use one of my USB-C peripherals it was a pain. For example I wanted to use my portable external monitor with my laptop. Both are "USB-C" however the issue is that USB-C describes the physical connector and not much else. I already new my laptop supported DisplayPort Alt Mode and I knew that was what the display was expecting (rather than being USB display adapter). However, I then ended up digging through the box of USB-C cables testing them until the third cable I tried lit the screen up. This was the general experience with my Thunderbolt M.2 interface as well. I don't have much that takes uses PD but as I understand that's yet another dimension of permutations.
Without intimate knowledge of both devices /and/ the cable it's hard to say what any combination of "USB-C" parts will do. Even OEMs fail to get this right. I friend recently told me of buying Dell laptops which offered a dock as an option. Unfortunately, the dock expected Thunderbolt & DP MST while the laptop only supported USB3.
My personal opinion is that the relative lack of USB-C in a highly competitive, consumer market like DIY Motherboards is likely because even after 10 years the consumer demand is just not there. When judged the more lofty aspirations of USB-C that are being expressed here (replacing most if not all USB-A, HDMI, DP, Thunderbolt, and lower wattage power cables), I consider USB-C to be a failure.
