I would also suggest you use a ferrule cleaner every single time you touch
an end

How about using the built-in Digital Optcis Monitoring (DOM/DDM) in
modern SFPs?  Assuming your switches/routers and SFPs support it, you
can read the received power level right from your switches/routers.
The cost might be zero if you already have capabile equipment...

Combine that with a flashlight for identifying strands, and it might
be all you need...
