The next best alternative app is surely SD Maid 2 SE (there are several versions, use the “2 SE”).
But note: this app has more functionality than CacheCleaner and allows also to clean up “unused data” and other stuff. When you use it without thinking you can produce serious data loss. In my case it deleted the downloaded maps and the voice of my navigation app which have been stored on a probably bad place. And you notice this never in that moment but later when you need it. My advice is: let it never delete something automatically, always have an eye on what it will be doing.
I’m regularly using Cache Cleaner (also downloaded from f-droid) on my Mi8 (dipper). It’s working well on T versions of /e/os: from 1.14 to the last one, 1.21-rc-T.
Just check the accessibility options in Settings.
