Why so many VLANs ?? I would put phones and your and your wife’s PC in same VLAN or are you trying to say that you don’t trust your wife ?? 
Kids camera in the same VLAN as your IoT devices, office stuff can go in separate VLAN.
I can recommend you VLAN guide from pcunite so you became familiar with VLANs and anav have great tutorial.
