ONE, do not create multiple SSID for according to its functionality (voice, data, etc) if SSID is used by same user group. I will keep single SSID for all of these. Also user will use single device (BYOD) for all of these functionality (voice, data, video) & difficult to have seperate SSID any longer (old days cisco recommend seperate SSID for voice where all 7925 phones connect)
Typically you would have different SSID for Guest as user group would be different & typically you need to give internet access & nothing else.
Below post should give you a clear idea how much overhead it will add when you creating multiple SSIDs
