I am involved with situation where I am faced with having to install an
interior remedial french drain system ( fortunately only about 20 feet
) . Is it worth saw cutting the concrete ( I am having concrete cutting
sub on the job for some coring elsewhere ) or should just use rentr
electric demolition hammer ?

I think a hammer is faster, and less messy, particularly since residential
slabs aren't very thick.
With a saw, you generally need the hammer anyway. The saw is needed,
though, if the edge
quality is an issue. I wouldn't think that would matter on your project.
