You can use SM for short runs, you just have to match the optics to the cable/distance you're looking to use. Tons of very fast single mode optics out there that only expect <300m runs.
That said, it's likely not worth it, given that cabling is typically viewed as a ~10 year investment, and if you're installing OM4 Multimode fiber in a house you're not likely to hit the limit of that fiber within 10 years even in extreme use cases.
