It depends on the wall materials and thickness. It may not reach the far corners on upper and lower floors.
You will likely also see significantly reduced wireless speeds. At the moment with best in class wifi you may be able to reach 1.5Gbps near the router, but that could be 200Mbps or less a few rooms away.
I agree with others that you should run cat6a to all rooms. But atleast run to each floor so you can connected wired access points for better wifi.
You should never use a wifi extender, and mesh may not work good if distances and building materials attenuate the signal too much. Nothing beats wired for reliability.
