I wouldn't go generic if I were you. A lot of people seem to go that route, but it doesn't really have a ton of advantages. It would be difficult to set it up in a way so that you can control every system of every airliner. I would just choose an airliner that you like and that has good software support in FS. For instance, I'm building an HS748. I fly it a lot in the sim, it's relatively small, and Rick Piper's HS748 addon simulates almost every system. It's also coded in XML, so it's easy to find the variables to link it to the sim.
I know of several addons, payware and freeware, that are home cockpit friendly. I could give you some suggestions if you wish.
