I would suggest watching the video as it shows you how too use the Block Element.
You’re design would require this:
1. Install the GenerateBlocks plugin:
https://wordpress.org/plugins/generateblocks/
Docs on GenerateBlocks are here:
https://docs.generateblocks.com
2. Enable the Elements module in Appearance > GeneratePress
3. Create a New Element -> Block in Appearance > Elements
3.1 In the sidebar set the Element Type to Page Hero
3.2 In the Editor first add a GB Container Block – in the sidebar settings you can add Spacing > Padding and Colors > Background Color.
3.2 Inside the Container Block add a GB Grid Block -> 2 column. Note each column is also a Container Block so you can add spacing and color too if required,
3.3 In the right hand column container add a GP Dynamic Image Block, set this to Display the Featured Image:

3.4 In the left hand column add a GB Headline Block, set it to a H1 tag, and sets its Dynamic Data to display the Post Title

3.5 Add more Headline Blocks for each of the post meta you want to display.
4. Set the Display Rules to the Posts or pages you want it applied to.
That should get you started
