ELI5 guide for setting up wifi? overwhelmed by options

Router Archer C7, Flashed 23.05.5, internet working, have access to webinterface.

Wireless overview has 4 items: radio0 QCA8880, SSID, radio1 QCA9560, SSID

I want to setup up a 2.4 guest for security cameras and 5ghz for home devices.

Have no idea which is what and what. No idea what any of the options should be set to.

Also my Windows network share does not seem to be working
