Try this on your existing cameras before paying for an official one. We test out two older cameras we had lying around, one official model, and one VERY unofficial, using the Switch 2's built-in USB camera testing tool.
While many third party cameras are compatible with Nintendo Switch 2, even with a USB-A style plug, some will not display video even if they're still functional and work with other, older devices.
Also, some that work just fine will threaten to eat your family. It's a fine line. Choose wisely.
