Right now, I have 258 tabs open in my main window, of which I’m actively using at least a dozen, and will use another few dozen within a day or so. (Probably should go through and clean out a hundred or two.) Most of my family is some degree of tab hoarder as well (my eldest sister regularly has over a thousand tabs spread across a few windows).

Get the "tab stash" extension, you can stash your tabs instead of nuking them. That way you can go back a few months and find things that would be tougher to find through history or other means.

Yet another tab management (YATM) recommendation here. I use the OneTab extension to help me manage tabs. In a recent update, they added the ability to:

A) name tab groups;

B) lock specific groups which mimics the capability of bookmark folders (clicking a link doesn’t remove it from the group).

The extension has helped me reduce the number of open windows on my laptop, among other productivity improvements.

I used to do this too, then I got a bookmark save service (Pocket). Now whenever I see something that I have the reaction of keeping the tab around, I just save it and close it instead. Makes browsing lighter. I do still have around 20 tabs open normally, mostly things that don't fit in the "bookmark save" workflow, but definitely better than the 100+ tabs it used to be before.
