There's still the annoyance of wanting to hang on to some tabs, but not others. Bookmarking extensions are typically the answer, but there seems to be a problem with out-of-sight, out-of-mind. So once you've bookmarked a tab and closed it, the chance of going back to it isn't good.

I can probably count on two hands the number of times I've ever directly opened my bookmarks in about 26 years of browsing. The reason I still bother to bookmark is that most browsers these days allow you to type into the URL bar a word and it'll suggest bookmark titles containing the word, that works for me. Still think bookmarking needs a paradigm shift in how we manage and organize the data.

It might fit your style to combine pinned tabs with a tab group extension. The groups are named and you can switch to them with a shortcut and pinned tabs are obviously visible everywhere.

EDIT: I am using the Simple Tab Groups extension on Firefox.

I wrote a script that opens a random bookmark. I set it to run every day when I know I'll be taking a break.

Now I can safely close tabs, having successfully satisfied my brain's objections.
