As far as I know, 3FR files contain image data that need to be processed to get an FFF file. FFF file is the Hasselblad RAW file format with all calibration data applied.
IPTC, calibration data, HNCS (Hasselblad Natural Colour Solution), etc, are in the *.FFF files, created by Phocus (digital images) or Flexcolor (scanned images).
In macOS I see the image and the preview in "Vista Previa" (I do not know the English translation, it is the program with which macOS visualizes all types of files).
I don't know if it has embedded jpg or macOS supports FFF.

Q. Why are there 3FR and 3F files? Why can’t captures be saved directly as 3F files?
A. 3FRfilesconsistofnativeHasselbladrawdatathatcontainsahugeamountofinformation,particularlywhen compared to 35mm digital files. This is essential to produce the level of quality expected from Hasselblad products. It follows that a good deal of computing power is required to extract the maximum in the shortest pos- sible time. To avoid diverting the camera’s activities to image processing, the combined advantages of Phocus and a workstation are used instead. 3FR files are then processed into a complete and workable raw format that can be saved, adjusted and exported, namely, 3F.
Q. What’s the difference between 3FR and 3F files? Should I keep them all?
A. A3FRfileisthenativerawfilecreatedbyHasselbladcamerasandremainsinthatformatwhenstoredonaCF card. When loaded into Phocus, however, various corrections take place based on the hardware configuration
of the camera used. This processes the 3FR file into a 3F format file and creates a high quality preview (size according to settings in Preferences). As this is an improved and specifically-tuned file, the original 3FR file can be discarded. You may, of course, export 3F files to TIFF, PSD, JPEG etc., and just keep those but if you have the space, retaining the 3F files could be good insurance to be able to re-process sometime in the future.
