Ideal location would be as close to the center of the space as possible. Also useful to know what the material used in the construction is. Things like concrete/plaster/stucco can inhibit Wi-Fi signals more than drywall and wood.
I’d suggest you put it where you want it. Then if you have problems consider replacing the ISP router with a mesh router and install mesh points in other locations to fill out the Wi-Fi coverage.

My ~1500 sq ft older home has stucco on the interior walls. Our mesh router is in the living room, next to the TV where the Xfinity cable comes in. The Wi-Fi coverage in my bedroom leaves something to be desired. I have a mesh point halfway between the router and the bedroom and my Wi-Fi rocks.
