What fuses should I set in order to use all the 32768 byte of Flash memory correctly?

Using the "minicore" Arduino core is the recommended way of using an Atmega328PB chip (or indeed an Atmega328p chip) with Arduino environment if you do not require a bootloader. It will set the fuses correctly for no bootloader operation. https://github.com/MCUdude/MiniCore

You disable BOOTRST. That's it. The "ultimate manual" you refer to is the datasheet which is currently at https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-7810-Automotive-Microcontrollers-ATmega328P_Datasheet.pdf.

If that link doesn't work, try Googling "atmega328 datasheet".
