Unfortunately the 6s is now a retired device. No device today can run a modern operating system with that low of a base hard drive. There truly isn't an option besides upgrading to a newer device with more memory.
The phone will work as a phone and stock apps will work for the foreseeable future. Added apps and anything requiring updates will cease to function at some point.
