FreeFileSync: Is FreeFileSync free?
Yes, open source and free. A paid Donation Edition adds convenience features such as parallel sync and portable installs.

Very little on modern Windows. The measurable gains come from clearing caches and controlling startup programs, not from the registry.
FreeFileSync: Is it a backup tool?
It synchronises folders and supports versioning, which covers many backup needs, but it is not a managed cloud backup service.
CCleaner: Is CCleaner safe?
It is a mainstream product from Gen Digital, though a 2017 supply chain attack distributed malware via an official build. That was resolved, and it remains a fair reason some administrators avoid it.
