If you don't want to run CO2 on this tank, then you need to stick with a "low tech/ low light" setup.

I'd definitely stick with a single bulb rather than dual bulb T5HO fixture. A dual bulb T5NO (Normal Output rather than High Output) would be another option.

I think dwarf sag should grow well with that light level.

It's very hard to find a variety of dwarf sag that won't grow 6-8" though. You might have better luck with Helanthium tenellum 'narrow' (formerly Echinodorus tenellus 'narrow') as it usually maxes out at 2-4" tall.
