I agree with John G4ZTR: Don't just hang a messenger wire (what your
steel wire is called) onto your tower and load it with coax and
control cables without considering the sideways force this will impart
on your tower, guyed or otherwise. It's best to go with your on-ground
alternative. If you can thread the cables through a PVC conduit, even
a conduit lying on top of the ditch, you get even more mechanical
protection for your cables.

I don't feel competent to comment about lightning strikes and
earthing, but
your proposal has some engineering issues:
The catenary of wire plus control cable plus coaxial cable will be
heavy and
will exert a sideways pull on your mast. Under windy conditions the pull
could increase and vary. Are you sure your tower can cope with the extra
load ?
