During months afetr I asked this question I was able to piece together some experience from various sources that now allows me to answer it, at least partially. I'll probably be editing this answer in the future and adding new items to the list.
The goal was to be able to use gazillion of ZBrush sculpting tutorials from Youtube and use them as a learning tool in Blender Sculpt mode. The conclusion is, in order to understand them, you have to learn ZBrush, there is no way around it. But you don't have to download and use the program itself, you can simply watch a few beginner tutorials. The best way to familiarize yourself with ZBrush basics is the latest playlist by Pixologic, published on 24.06.2016:
ZClassroom - How to Start with ZBrush
Another source that confirmed you can find some equivalents is a book "Blender 3D By Example":
