Page (e.g., "About" page) like Post?

Is there a way I can make my “About” page, for example, have the same look as Posts? That is, it would help if I could just have a featured image, sidebar, and the standard editing space where I can just add body text, Heading tags, add media, etc., without using Page Builder. Unless there is some kind of block in Page Builder that will let me just put in all the content as if I were editing in the regular WordPress page editor? One of my main problems is that I want to have the default .td-post-content body text. Most of the blocks I’ve found in the TD Page Builder seem to default to different body text styling…and I can’t find anything as flexible for editing a long page of content with multiple chunks of text, headings, graphics, and links. Thanks!
