What parts are used alongside the ESP-12F?

The AMS1117-3.3, ADS1115IDGS and CH340C appear in the most repositories here.

Which microcontrollers do boards using the ESP-12F use?

Most are built on ESP8266 (12) and RP2040/RP2350 (1).

How big is a typical board using the ESP-12F?

The median is 70 × 62 mm, and 69% are two-layer designs.

What is the most popular open source board using the ESP-12F?

By GitHub stars, Mideahvac dongle by reneklootwijk, with 74 stars.

Can I simulate one of these boards using the ESP-12F before building it?

Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
