I rely on AppZapper for this. One-click delete of apps and all related files. https://www.appzapper.com/
It took forever. When I was done with the project I “uninstalled” everything and then deleted every single file and folder from the list and manually poked around to see if there was anything lurking that I might have missed. I thought for sure I’d won.
About a week later I got a notification that Adobe Creative Cloud was requesting keychain access.
I’m convinced it’s un-uninstallable.
