If you want to make use of the full 500mb as best as possible over wireless then you're going to want to look into a tri-band system.
If you're not too bothered about speed over wireless, but just want good coverage, then you could look at a dual-band system instead.
for tri-band check out the TP-Link Deco M9 if you're happy with AC systems, or check out the Deco x60 if you want to future proof and get a "wifi-6" system
for dual-band check out the Deco M4/S4/M5 for AC systems or the x20 for wifi-6.
Alternatively, something from the Asus range - for wifi-6 check out the ASUS ZenWiFi AX Whole-Home for regular AC check out the AC3000 Tri-band Whole-Home Mesh WiFi System
