I have previous experience with RB2011UiAS-2HnD-IN and CRS125-24G-1S-2HnD-IN routers.
I just upgraded my Verizon FIOS speed to 300/300 Mbps, and I bought CCR1009-8G-1S-1S+PC. My WAN connection is still DHCP with RJ45 coming to my house.
I have noticed few issues:
Quick Set is not working if I choose Router -> Eth1 -> Automatic
I went another way and used MikroTik CCR1036 router configuration like an example.

Eth1 - Management port
Eth2 - LAN with DHCP server
Eth3 - WAN with DHCP Client
I modified steps a little bit to create DHCP client instead of static IP, and use my WAN DHCP address (71.121.244.191) in the IP Firewall NAT.
/ip dhcp-client> print
INTERFACE USE-PEER-DNS ADD-DEFAULT-ROUTE STATUS ADDRESS
I completely agree with your comment. I wasn’t ready that CCR1009 setup approach is different compare to RB2011 and CRS125.
I was trying to use Quick Set for a temporary configuration to test my ISP speed, DHCP lease and NAT. It was difficult to search for clues without internet connection while I was configuring basic firewall and NAT rules. I had to call my ISP each time to break DHCP lease when I was switching routers. (stupid )
