I have never tried a factory reset from android, I would just do it from twrp personally. Also thought I'd mention since I forgot, I haven't tested this on cm, but last time my sdcard/internal storage had less than a GB free on amazon os, I was slowing down pretty bad too. Feel free to factory reset from inside of twrp, it shouldnt do anything harmful, also might wipe cache and dalvik cache while your at it. I would definitely make a backup though before updating purely because some people have had selinux issues where they have had to wipe internal storage to get it to flash, and since that would destroy the rom and you are without a PC that would suck, because by the time you find this out you would have wiped your os already.
