There are so many routers in the market it's impossible to recommend any particular one. You'll want to decide if you want a single router or a mesh system.
We have a two story house, and I've used a mesh system for over 7 years. My first one that I had for several years was a Netgear system, but it would often require a manual restart of every node when it installed a firmware update. I've since gone with a TP Link Deco mesh system that's much more reliable.
If course, if your house isn't all that big and is a single story abode, then a single router might be a better (and cheaper) option.
There are WiFi7 systems that recently hit the market. Going with one of those would be kind of a "future proof" for your WiFi. I have a WiFi 6E Deco system that works fine, and doesn't get "choked" by a large number of devices all clamoring for attention.
I also have Cox as my ISP. I would recommend against getting a router from Cox...the last time I looked into what they offered, they were only offering WiFi 5 when the rest of the industry had already moved on to WiFi 6.
Just my $0.02 worth.
