I am similarly getting into C from the OpenBSD perspective. Checkout the OpenBSD source and the port source. I look at more recently added folders like httpd and doas for example. Also I like httpd because I tend to understand the topics itself so if there's anything you already understand find THAT C code. That's why the ports code is helpful. More smaller things to choose from.
