WordPress.org has extensive documentation on blocks. Below are some common blocks that you will probably want to use.
Paragraph Block
The paragraph block is the default block that appears whenever you press enter. If you want another block, type “/” and enter the block’s name, or alternatively, just type “/” and hit enter to view all block options.
Image Block
The image block is used to add interest to your pages and posts. It has many settings that can be used to resize and position its display.
Media and Text Block
The Media and Text block makes it easier to combine media (images or video) with text for a combined display.
Columns Block
The Column block displays content in vertical columns. Each column automatically becomes a Column block and any block nested beneath it is displayed in a column.
Row Block
The row block makes displays its underlying blocks in a horizontal or vertical row. For responsive display, the row block is sometimes preferable than the columns block.
