Can I use the card reader with the SDXC card?

No, the CFexpress card reader is not compatible with SDXC cards. You would need a separate SD card reader for the SDXC card.

Which should I buy first as a photographer?

Buy the SDXC card first for immediate storage needs, then consider the CFexpress reader later if you upgrade to CFexpress cards for professional workflows.

Are there cheaper alternatives to either product?

Yes, basic SD card readers cost $10-20, and smaller capacity SDXC cards start around $30. However, these SanDisk products offer premium performance and reliability.
