Hi Danny, from another site, somewhat dated but:
” 24sF is a transmission method to make 24p compatable with 1080/60i processing and switching equipment. It will display on a CRT monitor as 48hz. The lines of the 24p image are alternated across the two fields just as in interlaced video.
The major difference is that the lines are not temporally separated in time. They are pulled from a single progressive frame. Therefore the sF process can be completely reversed back to 24p. 24sF was intended as an internal format for broadcasting and production although several consumer scalers now support it.”
In other words, your NLE such as Premiere will handle the footage you load (interlaced, progressive) and so far on my D800, the ingest is automatic plus I convert everything to CineForm (4.2.2 10 bit) which some might consider over kill, others not so much.
