If you're looking for a comprehensive beer style guide, I'd recommend checking out the Beer Judge Certification Program (BJCP) style guidelines:
https://www.bjcp.org/bjcp-style-guidelines/
It's a pretty comprehensive beer style guide, for those who want to go a bit deeper into all the variations of beer, with a decent amount of detail on each style.
From American Light Lagers through to some obscure and historical styles such as the Piwo Grodziskie, or Sahti... And everything in between.
