What is the best duplicate file finder, that preserves my source of truth? (alien.top)

Having been so meticulous about taking back ups, I’ve perhaps not as been as careful about where I stored them, so I now have a loads of duplicate files in various places. I;ve tried various tools fdupes, czawka etc. , but none seems to do what I want.. I need a tool that I can tell which folder (and subfolders) is the source of truth, and to look for anything else, anywhere else that’s a duplicate, and give me an option to move or delete. Seems simple enough, but I have found nothing that allows me to do that.. Does anyone know of anything ?

I’d like to find something that has that capability- so I can say multimedia/photos/ is the source of truth - anything identical found elsewhere is a duplicate. I hoped this would be an easy thing to as the ask is simply to ignore any duplicates in a particular folder hierarchy..

Well that's possible with a lot of deduplicators. But I'd take a look at duff:

https://manpages.ubuntu.com/manpages/xenial/man1/duff.1.html

https://github.com/elmindreda/duff

The duff utility reports clusters of duplicates in the specified files and/or directories. In the default mode, duff prints a customizable header, followed by the names of all the files in the cluster. In excess mode, duff does not print a header, but instead for each cluster prints the names of all but the first of the files it includes.

 If no files are specified as arguments, duff reads file names from stdin.
