My bookmarks shall be my first suggestions in my urlbar, so a bookmark is either frequently used or something I want to refer to specifically because of its content and quality.
Everything I want to read later is placed as leftmost of my top-level tabs. Opening tabs is right to my current tab without visiting them immediately. I visit them by closing the first and immediately get the next unvisited. My previous tab is still my top-level.
If I do not have the time to read everything leftmost, I may open a new window.
If there is something really worth it to be saved, it gets elected a bookmark.
// after reading my own answer:
My bookmarks are curated across years, my session might life 1 hour to multiple months.
Firefox allows me to even transfer my tabs across new devices. Each time i finished a task and close tabs, I am able to read on of the tabs to the left. This is work time.
