Couple of data sets to consider
If you want raw data, you want either AIXM or ARINC 424 files. Processing them will need some programming capability, or at least access to a tool that provides processing capability on that data.
Eurocontrol have some data available in AIXM via EAD and has runway data for pretty much everywhere. It's missing some approach/departure stuff however. The quality of this data is pretty reasonable from what I've seen. For this kind of application you probably just want a static dump: SDO is what you're after. IIRC, access to that is a few thousand euros a year.
If you want ARINC 424 that is used for training simulators, FMS and other applications where accuracy and completeness is important, your best bets are Jeppsens, Lufthansa or Navigraph. I understand Navigraph do not provide all the approach/departure information for categories that would include smaller aircraft. I know a few operations software providers cite Lufthansa as their data source for pre-flight planning tools. Costs for these data sets are - as I'm sure you can imagine - considerably higher than Eurocontrol. Worldwide data is in the mid-"tens of thousands" of euros range, minimum.
As it's quite expensive data to get, it needs some coding skills to make sense of, and there's a fair bit of paperwork involved, you might find it easier and cheaper to simply go to these companies and ask them to do the analysis for you.
If you already have pre-flight planning software that uses this data, you might want to talk to your vendor to see if they might be able to help you - they already have licenses for the data, the skills to process them, and an incentive to help you as much as possible.
