There are also several 16-bit families, but they don't seem to be worth covering in great detail: the prices of 32-bit and 8-bit chips are already pretty close, so the case for a proprietary in-between solution seems pretty weak.

Notable omission in my opinion: The nRF line of microcontrollers is really popular for low-power wireless applications, and not very expensive or hard to use for a hobbyist. The proprietary BLE stack is avoided using NimBLE, and the offical SDK can be avoided the same way STM32's can. It belongs in somewhat of the same bracket as ESP32, but it's a competent choice for low power/simple applications even if you don't need the radio.
