    I’m creating a FSE theme and seeing lots of classes like is-style-shadow-light, is-flex-layout, alignfull, etc. Where can I find documentation so that I can understand what classes are available? Is there any kind of reference?

    There is no official guide on all of the available classes. But there is a guide to layout classes on the Developer Blog. That will cover things like flex classes.

    You shouldn’t need to target the .align* classes since WordPress will handle the CSS for those with block themes.

    Anything that begins with .is-style-* is a custom block style created by the theme (or a plugin). You can learn more about block styles in this guide on the Dev Blog.
