Just to mention a tool that I did not see elsewhere in the discussion: I store my bookmarks in the weirdly named BookmarkOS (https://bookmarkos.com/). It costs a nominal amount a year and provides just the right level of organization for me.
Recently, I have been storing groups of tabs related to a subject in the Firefox Simple Tab Groups extension. The UI is a bit hokey, but it does let me context switch between complex tasks quickly.
