Fluid Engine for long text pieces

I built a small site as a class project -- slowspeedrail.com -- using the classic editor, and now I am expanding it into a larger capstone project. Each of my pages will include a lot of text, with photos in between (think of this as a master's thesis presented online). 

Using the classic editor, I was able to paste in a large amount of text, and then go back and easily add photos in between. Unless I'm missing something, the process in fluid engine is tedious. Each time I want to add a photo, I need to cut all the text below it, create a photo block, add the image, then create a new text block below it, and paste that text. For an example, slowspeedrail.com/slow-movement is a rough draft of a page I was working on. 

Am I doing this right? Unless there's a workaround I am missing, I'm thinking I either need to continue doing it this way, or perhaps set up my pages as individual blog posts, so that I can use the classic editor. 

Many thanks for any advice you can offer.
