What a hefty piece! This one has a ton of value. When you mentioned Notion, my eyes did a double take. Of course!
I used to work for a hip startup digital bank who used Notion as a huge how-to database and I loved it. I never thought of using it in my personal or now freelance writing life.
As a bonus, Notion also has a web clipper chrome extension you can use in place of Instapaper, saves the extra app.
