Do you have experience with any other microcontrollers? With programming in general?

Was that using an example from CubeIDE?

What debug messages?

You mean you have put printf statements into your code?
printf is a standard C function which sends output to stdout.
On a "normal" platform like a PC, output to stdout will appear on the user's console - but an embedded system like a Nucleo board doesn't have such a thing.
So you have to decide where your stdout output will appear: you do that by writing suitable code - commonly to a UART.
Before getting involved in the complexities of printf and stdout, I would strongly suggest that you get basic UART output working using HAL_UART_Transmit:
https://community.st.com/t5/stm32-mcus/implementing-uart-receive-and-transmit-functions-on-an-stm32/ta-p/694926
At the end of that article, it will direct you to the next step - using that to get printf working to a UART.
A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
