My garage is set in to 5ft of soil at the rear & right hand side. I lagged it with 2 layers of the thickest damp proof membrane I could find before back filling with rubble then soil. It works fine. I drilled 2 holes at the base of the back wall for 4" waste pipe to go under the concrete floor. Didn't think they were working until last week when we had a particularly heavy spell! :eek I built the soil retaining walls a foot thick to cover my ass.
I would go with your option 1 myself if you are happy the wall is strong enough? Drape the lagging over the footing in to the soil & fill with gravel or whatever you decide to use.
