I organize my tabs by topic window (small project, chunk of work for a larger project, related idea) then kick them into onetab as a bundle with a short description when I’m done with whatever it is I needed them for.
I typically have 5-30 tabs open in topic windows at any time but I can open onetab and ctrl-f to find anything I’ve saved over the last 7 or 8 years. There must be 5000 tabs in there at this point.
