Upgrading a church network

Hi NightWolf1020,

Welcome to the community! :) 

For the firewall router, I suggest you the FVS336Gv3.  You can allow or block services like FTP, RDP, etc, on the FVS336Gv3.  You can also block certain keywords that you don't want to be access on the internet.  Be reminded that it does not have the capability to completely block HTTPs websites. 

For the switch, I suggest you the GS724Tv4.  The GS724Tv4 is a 24-port smart switch that supports VLAN configuration.  You can create VLANs to segregate the Admin, DayCare and Guest networks.  

For the access point, I suggest you the WAC730.  The WAC730 also supports VLAN wherein you can create a wireless network for the Admin VLAN, DayCare VLAN and Guest VLAN.  

For the storage device, I suggest you the ReadyNAS RN422.  The RN422 is a 2-bay NAS that also supports VLAN.  I believe the storage unit is solely for the Admin network access to backup important files. 

About the maximum length of the ethernet cable, it should be less than 100 meters.  Its because if its beyond the 100-meter length, the signal weakens. 

Here below is my suggested network setup for the church:
