Not specifically a recommendation for doorbells, but if all you need is a relay with an ESP inside that you can flash to ESPHome et al., Sonoff or Shelly products are pretty neat ready-made options that incorporate a power supply from mains (and sometimes have some DC powering support too), a relay and a case.
Some models have an option of measuring temperature and/or power consumption as well.
