I’m finding that I use locate more and more for this sort of thing. Of course, it produces a lot more output, because it looks at the whole system. But, it is still much faster than find because it runs on some kind of index or something, and it is easy enough to grep out the directory I’m interested in, if needed.
locate is nice, but I think that on most distros its index is only updated once/day (unless you adjust the cron job that updates it more often). Most of the times I'm trying to find something, I haven't modified it recently, but it can definitely lead you astray.
One can just run 'sudo updatedb' to refresh it. Super fast if it's already on a schedule. I think mine is set to update every system update, so I just have a habit of running that before I use locate each time.
