> Any method that I've found to clean them up (exporting the originals, deleting them from the library, and then re-importing the JPEGs only seems easiest) will lose all of the years of metadata that I've built up in the library.
The open source tool osxphotos (https://github.com/RhetTbull/osxphotos) can help with this. You can export the JPEG images while preserving metadata using the thrid-party exiftool utility:
This exports all images that have a raw pair but skips the raw component then uses exiftool (https://exiftool.org/) to write the metadata (keywords, etc.) to the exported JPEG files. You can then re-import these into photos either by dragging them or by running `osxphotos import /path/to/export/*`
Both the export and import commands have many other options for controlling export directory, etc. `osxphotos help export` or `osxphotos docs` to open docs in browser. (Disclaimer: I'm the author of osxphotos)
