Hi, I'm conceiving a new Cyclone V E based board implementing a 5CEFA7F23, a DDR, a SRAM and a Flash memory. I wish to configure my FPGA with Asx4 configuration, so I need a QSPI NOR Flash for ...

Cyclone V will support (boot from) any of these devices - providing they meet timing. All the options you list will. You can program them with the Quartus programmer, either directly (see figure 7-15 in the cyclone v handbook (https://www.altera.com/en_us/pdfs/literature/hb/cyclone-v/cv_5v2.pdf)) or indirectly via JTAG (see figure 7-13 in the Cyclone V Handbook) using a .jic file. Altera's EPCQ parts are expensive by comparison. However, they are 'simply a QSPI Flash'.

The 'only' issue you may come across is programming them from the Nios2 flash programmer. However, there is a work around for this too. If you're not looking to boot a Nios from your SPI FLASH then this is not an issue.

Cheers,
