Want to optimize my gig speed wifi router

I researched and purchased an Arris SURFboard SBR-AC1750 wifi router and am pretty happy with it.   I researched cable modems as well, and as luck would have it, my ISP had an Arris Touchstone CM8200, so this is now paired up with my SBR-AC1750 wifi router.  The router has a 4 port switch/hub built in and this feeds out to my network switch and then throughout my house which is hard wired with CAT6 cable. As I enter the router menu, there are all kinds of settings and I would like to completely optimize it for my gig speed internet cable modem service.  What do you experts recommend? Also, if you have suggestions for the cable modem settings let me know as well.

There are not too many settings for this. Your modem is controlled by your ISP and they should put out the rated speed.

Connect by LAN ports and Ethernet via a short cable to your router. That interface is automatic.

For wireless use the 5 GHz AC band and set your computer to use this band.

Problem with many modems is the issue best described as "buffer bloat".
To get timing right. one can prioritize shorter packets, icmp packets, ack's SYN/FIN packets. at the expense of large packets.
There is scripting for this: wondershaper.  Which only works on Linux systems.

For WiFi only allow WPA2, AES, (either PSK or Enterprise). and At least disable 802.11a and if possible also bg.
(which would boost your speed because there is no regular switch down to 1Mbps to pickup 802.1A devices ...
if you have such devices, be sure to replace those).  Same is true for bg which start at 54Mbs with speed negitioations.
For g and higher the speed is about 100Mbps  to start communicating.

Besides being sure that all interfaces match there is not a lot to do....

One thing to do is to make sure the router throughput is adequate. My Cisco routers have 800 - 900 MBits/sec internal throughput
