Content Template not displaying when adding new post

Yes. But I see no option to take the page and clone or duplicate it into a post.

You can only clone a post to another post, same for the pages, they are different post types.
If you want to create a post template, you should create the layout in a post, not on a page.

But anyway, you can also copy all content from the page and paste it into a post. Here’s a video show you how to do it:

It’s because your page’s content container is set to full width, while your post’s content container is set to 800px via a layout element.

If you want to same layout, you need to remove that layout element which limits the content width of a post.

Go to appearance > elements, look for a layout element assigned to posts, and set its status to Draft or pending review, and let me know if the issue is fixed.

Can I see one of your posts?

Hi Matt,

Try creating a Hook Element hooked to wp_head. Display it on your preferred pages.

Then, add this code:

<style class="custom-cat-style">
.site-content .inside-article {
    display: flex;
    flex-direction: column;
}

header.entry-header {
    order:1;
}
</style>

Let us know how it goes.

You’re welcome, Matt!
