Mesh systems are great - I have the Google/Nest mesh and have no problem getting Wifi throughout my house. The Cox Panoramic mesh pods would work also, but I've heard mixed reviews on these (at least compared to Google mesh or Eero mesh).
I have the Linksys Velop and absolutely love it. I just plugged it into one of the Ethernet ports and it was up and running. It has a separate network from the Panoramic WiFi and will act as it's own DHCP server for that network so you'll have two different networks to connect to. But I haven't had a bit of trouble with it.
