When I was a studying I also thought there is value in "finding perfect setup". That I will find that one job and I will be able to master one thing and one setup. Then workplace reality came in... One year I have to use MacBook other Windows then mix up project with a lot of linuxy stuff. One thing I learned well is to learn quick and get accustomed to different interface, different keyboard, different language. Maybe I am not writing above 80WPM but give me any keyboard and in 15-30 mins I am going to be comfortable with it. The same with cars, get in, first 10-15 minutes of driving and after that I use important controls intuitively. I don't see value in mastering specific make of a car, it is just a tool.
