I like ESP8266 and ESP8285 and ESP32

The Nokia 5110 LCD has 5 control lines; the interface is of the type SPI. Mostly, when no other SPI devices are used, the chip select can be connected to the GND, so 4 control lines stay over. To save Arduino pins, there is an option to use only 3 control lines, while the Nokia reset pin is connected to the Arduino reset. This works only when the serial monitor is used, not with a standalone Arduino.

The ESP-01 has only 2 GPIO's, so you need another board with more GPIO's. Then there is the required SPI control SW.

Perhaps an I2C LCD would be a better choice, that only requires 2 GPIO lines, and there is a nice Example in the Examples section for I2C control on the ESP.
