OBS streaming resources?

I've been streaming with OBS for about four or five years now, and I switched to multiplatform streaming about two years ago. So I understand the basics of connecting all the things, but I can't help but feel like OBS has tools that could help me elevate my stream production, like switching "scenes", creating a "BRB" screen, etc. I also work with a dual camera set up. I'm wondering if anyone has an accessible OBS resource to learn more about the platform, or even an OBS resource specifically for cam girls. thank you in advance!!
