Our network will consist of 5 access switches connected to a layer 3 core switch connected to a SG430. We will have several VLANS consisting of computers, VoIP phones, security cameras and card access readers. Total users will be around 100. We are fully cloud and no longer have any servers so no DHCP or DNS server. It appears my options are to use the core switch as layer 2 and let the SG430 handle the routing, DHCP and DNS or use the core switch as layer 3 and let the switch handle DHCP. Does anyone have a recommendation as to which setup will give the best performance? Am I missing any other option?
I prefer to put routing on firewalls and switching on switches.
It is also easier to manage DHCP on two SGs in HA (active-passive).

Valid point, but if you do so you definitely don't need to invest in "Layer 3 Switches". L2/L2+ will do.
