Increasing the Space on the Right
By default, Gutenberg comes with a lot of additional “baggage”. It’s a far cry from the clean, white interface that most writers enjoy. One way to get started, is to remove the right-hand side block that’s the default on every page. Here’s what it looks like:

Shortcuts for Headings
In Gutenberg, the familiar shortcut for creating a heading is gone. We used to be able to use “Shift+Alt+[number]” to indicate an H1, H2 etc heading. Luckily for those of us who want to keep our hands on the keyboard, there’s a new shortcut. I’m not sure why they couldn’t keep the old one, but anyway… To create a heading, append the one, two, or three hashtags to the beginning of a line and press “space”. If you use one hashtag, it’s a level 1 heading. Using two hashtags makes it level 2 and so on. This makes it a bit easier to edit long documents with a bunch of headings.Using Slash (/) for Inserting Blocks

I would have to admit, it is a learning curve. I think I still prefer Elementor as my editor. But like you, I gave Gutenberg a try, by transferring my personal site to Gutenberg, http://www.davisdre.com .
