Is the MB ASUS|PRIME B550-PLUS AC-HES R a good choice for AMD builds?

IMHO this motherboard is *perfect* for a budget build and upgrade; that's exactly what I used it for and it has impressed me. AMD's AM4 CPUs are still good choices so why spend more on a budget build?

Does this motherboard come with built-in Wi-Fi and Bluetooth?
