Simplest is what you were doing- just add niceties like DPC on top of the dwarf walls, DPM on the earth (keep the moisture content down in the subfloor void, chuck some gravel on it to stop it floating/flapping), noggins (stiffens the floor up very nicely), insulation between the joists and off you go
Nice thing with the dwarf wall- all the support is being done by structure rather than fixings. The fixings (skew nails) are useful while you're putting the joists in (so they don't move around) but that's really all they're doing. Much easier to level with the dwarf wall as well- slate or shim to compensate for undersize timber.
