If you are scanning the film for preservation, you should maybe scan at the
maximum optical resolution of your scanner. Film Scanners do a better job
with 35 mm film.

If you have the storage space for all of the TIFFs then that is the best
format to save your files. No lost or any kind.

However, High quality Jpegs are fine if you do not edit and resave them many
times.
Jpegs take around 1/10 the space as a uncompressed TIFF.

Jpegs only deteriorate from the original quality they were saved at if you
edit and then recompress them several times. Just copying the file does not
cause any more deterioration.

The amount of deterioration for the first compression is not usually visible
to the human eye if the compression is not too much. A jpeg quality of 90 on
a scale of 0-100 is usually not visible to the human eye.
