This plugin adds unopinionated utilities and components for the Gutenberg Block Editor. It's purpose is not to style the actual blocks which you can either do yourself or let WordPress handle for you with add_theme_support('wp-block-styles');. If you want a plugin that will let you style the actual blocks as components, have a look at tailwind-gutenberg-components.
Personally I encourage you to try working with WordPress own block styling as it will make it easier to include your entire stylesheet in the block editor and have your styles applied on both the front-end and the back-end.
By using the core styling and this plugin you're basically left with minor adjustments, styling buttons and defining gutters between blocks. All of which are too opinionated for any plugin to handle.
Block Color Palette utility classes has-X-background-color, has-Y-color.
Low specificity foreground color components for the background color classes has-X-background-color. It will pick a foreground color with high contrast so a dark color is used on light backgrounds and vice versa. This might require you to inherit the color value on some block subelements.
If you need to be more specific, just add a custom style to your stylesheet, this is just meant for a decent out-of-the-box experience.
Block Font Size utility classes has-X-font-size.
Add the otherwise missing alignment components for alignwide and alignfull as well as responsive versions of alignleft and alignright.
This styling depends on the wrapper having a width and then alingwide and alignfull will break out of it. You might also need to hide overflow-x on the html element.
Fix some bugs in the block editor back-end that haven't been fixed upstream and reset the alignment styling added here so they do not break the editor experience.
This assumes you're enqueuing the entire stylesheet with add_editor_style.
