I made a Freelancer spreadsheet/database (attached) that lists all possible trade routes in the game. It lists commodity, start/end locations, start/end sectors, run length, and profit margin. Sortable of course. It's about 6.8Meg unzipped.

The last page has all routes of any length, and the rest of the pages are broken out by number of hops.

You can use it to answer questions such as What is the highest profit run? ($1900, alien organisms[illegal] from RuizBase/OmicronBeta to CambridgeResearchStation/Cambridge, six hops)
What is the highest legal profit run? ($1440, Luxury Food from PlanetCambridge/Cambridge to LuxuryLinerHawaii/Sigma19, six hops)
What is the highest profit in one hop? ($630 Luxury Consumer Goods from either RopongiStation/NewTokyo or PlanetNewTokyo/NewTokyo both to AinuDepot/Hokaido)

And more situational questions like what's the highest profit from where I am right now to anywhere? or to a specific sector or location or distance. Or where can I get the most for my current cargo? Stuff like that.
