One site, two Editors? Why? And which one should I use?
Up until 2018, the Classic Editor was the only Editor and most long-term WordPress users loved it (possibly because those who didn’t love it didn’t stay on WordPress long-term).
In December 2018 WordPress moved to the Block Editor (also known as the Gutenberg) to move to a more visual experience. Here’s what they said at the time:
Say Hello to the New Editor
It’s a whole new way to use WordPress. Try it right here!
We call the new editor Gutenberg. The entire editing experience has been rebuilt for media rich pages and posts. Experience the flexibility that blocks will bring, whether you are building your first site, or write code for a living.
Do more with fewer plugins. 
Create modern, multimedia-heavy layouts. 
Work across all screen sizes and devices. 
Trust that your editor looks like your website.
Some people welcomed the new editor because they found it easy to learn and easy to use to do the things that they did most. Some preferred the original editor because they knew it well and because it allowed them more control.
So, at The Secret Reading Room, we support both. You can choose to use the Classic WordPress Editor or the Block Editor or move between the two.
Why should I read this Guide?
This guide walks you through how to use the Block Editor to make your posts look the way you want them to.
We’ve split the guide into three sections:
This explains what blocks are and what makes them useful to you.
This explains the mechanics of working with blocks. How to find the one you want, how to add to a Post, how to edit the content and format of a Block and how to move a block around in your Post.
This looks in more detail at the eight Blocks we think you’re most likely to want to use.
What else can I read if I want to know more?
WordPress offer free tutorials on wordpress.org. We’ve drawn on them to produce this Guide but, if you have more detailed questions or want to go into more detail about blocks other than the eight we’ve chosen go HERE.

As an initial comment, you need to either delete the “Featured Image” or delete the top image because it is duplicating the same header image on the post on the main feed, which is redundant and looks strange.
I like the layout, though, and I think that the way that you have it broken down works well in terms of organization.
I’ve deleted the Featured Image. I’ll leave them blank going forward.
