This is the user manual for the board https://www.st.com/content/ccc/resource/technical/document/user_manual/group0/6e/c2/81/e8/92/5f/41/cc/DM00368330/files/DM00368330.pdf/jcr:content/translations/en.DM00368330.pdf

>>Which pins to configure on the Cube MX ?

The Nucleo's VCP is LPUART1 on PG7 and PG8, so you'll want to use that, enable power on the GPIOG IO bank, and make sure all the solder-bridges are in order.

>>should i use an FTDI (usart to usb cable) ?

Shouldn't need too
