I see. I haven't explored the low-power states yet, the datasheet says 5µA is possible using hibernation and timer-controlled periodic wakeup. Was curious if those numbers are achievable.

On the ESP8266 I was able to get down to 16.3 µA deep sleep current. A lot of easy-to-use modules come with a USB-serial converter and a 5v-to-3.3v converter. These will draw a few microamps even when there's no USB connected - and depending on the precise hardware, some will draw far more than that. You should plan on buying a few different modules and de-soldering a few components if you want to achieve the absolute minimum current consumption :)
