A few months back ShutterSlim kind of made a splash here. The main thing it does is use AI to find similar photos and help pick the best ones. I've kind of continued down the stuff-I-need-myself rabbit hole and it now recompress videos to H.265 in place in Photos.app. It can do side-by-side or swiping previews of video recompression, showing the approximate savings. For me this let me slim down my library by another 80 GB. The other big change is that it's now free to try (10 photos groups, or two videos) if folks want to give it a try without paying. Here's the app store link.
