Stow keeps a folder on your computer and a folder on another drive or a NAS the same. Pick two folders, say what should happen and when, and Stow says the whole plan back in one sentence. The first run shows every file it would copy, replace or remove, and anything it replaces or removes is kept for 30 days.
For Mac (Apple silicon) and Windows 11. $39 once for 3 computers, with a 14-day trial that has everything working. And yes, there is a dark mode.
