The Gutenberg editor comes with a default set of blocks out of the box. They include blocks for inserting different types of content (common blocks), formatting, layout elements, widgets, and embeds.
You can check the list of core blocks here.
But if you need more content blocks like pricing tables, testimonials, and calls to action, you can install a Gutenberg blocks plugin like Stackable, or CoBlocks, which offers a lot of extra helpful blocks.
You can explore the new block editor by visiting the new Gutenberg editing experience page.
