I live between FH and Catford and recently changed roles so travel from Catford everyday into farringdon which is a dream journey. Always a seat no hassle and 30 minutes door to door. I walk home along either STandstead road or Catford Hill and it's very safe. THe streets are well lit and there are regular buses running too. As the traffic is always heavy in the evenings going into Catford you will find you have an audience of bored drivers so nothing will happen.

Which roads are you looking at? I am on Marler Road would be happy for company on the walk home in the winter months as the hubby sometimes frets, but I never take alleys or short cuts!

Avoid the underpass at the station as it'salways full of weirdos unless loads of commuters are crossing at the same time.

Also coming home after a few drinks I always go to Forest Hill as I know the taxi firm and they don't keep you waiting.
