For your purposes, your 8000 ft runway will probably do for most aircraft short of the heavies, or older large jets (707 etc).
In the real world it gets far more complex. The runway length needed for any aircraft on any particular flight will vary, in some cases quite a bit, based on the type aircraft, it's takeoff (landing) weight, and the "density altitude" of the airport at the time. With a high density altitude (0ver 3000 ft) your 737 could take up to 2000 ft more runway at high weights. Density altitude is the physical altitude corrected for temperature (and other factors).
As someone pointed out, a fully loaded 747 takes about 8000 ft near sea level, but Air Force one routinely operates out of an airport with a runway of only 8600 ft and an altitude of about 500 ft (KCNW near Waco, TX). But they don't operate anywhere near max gross weight! The up-graded engines also help.
But then, half the fun of this simulator is seeing how far you can push the limits isn't it?
