Here's an example: statistical methods. I'm a software engineer and was going to start helping with analysis tooling. Having characteristics and example use cases for many statistical methods helped me work faster and make better choices than needing to look things up. Generalized, cases where you can choose from one of a few options/technique and this choice is an expression of your professional opinion are good. What you memorize are the attributes of the options that you tend to make the choices on. It's hard to get across (and impossible if people don't want to believe it) the difference in speed/quality/accuracy that comes from having 3 attributes of 10 options at instant recall versus a few that come to mind right away and then more if you remember to try.
