I’m working on improving my software design skills, and it was recommended that I study existing well designed codebases. What are some publicly accessible codebases you would consider gold standards for software design?

There's a free book on this topic: The Architecture of Open Source Applications

Maybe that would be a good start. You can then pick a project to dive in.

As a more specific tip, I've done some hacks in Nginx long time ago and found it quite nice.
