I have a large shed (far too large to consider re-roofing) which has a
corrugated asbestos-cement roof that probably dates from the 60s. It's
in quite good condition but there are a couple of cracks and one 4" hole
where a pipe used to pass through.
It seems the repair options are either Flashband (+primer), an EPDM
patch, making a GRP patch, covering with a bit of corrugated roofing, or
using galvanised mesh and cement. What else should I be thinking of? Any
recommendations?

Rather than flashband I would be thinking about the fabric with mastic
tapes, Sylglas to DIY-ers or Denso tape to professionals. Together with
a bit of corrugated sheet of the correct pitch for the 4 inch hole.
Probably not galvanised mesh plus cement, too likely to crack over time.
