What version of Bluetooth must my device (smartphone) have to communicate with an ESP32 based project?

It depends on which profile you are talking about. Bluetooth is meant to be backwards compatible. Ble was introduced in 4.0

Not sure what you mean by "profile". I am using a NodeMCU-32S dev module.
