You can use GenerateBlocks to easily create that.
For the image, use an Image Block. For the description, a Headline BLock, and for the Buttons, a Buttons Block.
GenerateBlocks has Block settings to make it look like the one in your reference site.
You’ll find docs on them here: https://docs.generateblocks.com/collection/blocks/
Here’s a great instructional video on how to use GenerateBlocks: https://www.youtube.com/watch?v=R7fwJECtgSg
You can add these Block in Appearance > Widgets > left or right sidebar.
