Im debating getting this, pre buying a Asus router about 18 months ago I ran pi-hole on a pi4 which I also used as a NAS but my router had usb ports and could auto set dns and even had auto configure for certain things. I have no idea if it actually works though as I get ads on my phone for RU-vid. I have a spare Pi Zero W (though if I do use it I have a usb hub which has ethernet I will connect to it)
