Wired is more secure. You don't need to be very close to connect to a wireless router. You can repurpose any number of readily available household items to eavesdrop on wifi more than a block away. Especially if the owner has put up a high power network to cover the blind spots in his home.

There are 2 options that can sort of protect you (aside from encryption which you should be using anyway). Firstly get a router that allows you to set the output power level and set it to the minimum you need. 2ndly, use 5Ghz bandwidth as much as you can. It gets absorbed by the walls better and leaks less. 3rd, if you are really paranoid about it, put in a Faraday cage around (basically wrap your room/building in a metal mesh) or at least put one around the side of the router that should not leak.

For example, my main router is in a comer office, so I don't need it to cover the neighbor's side. I've put in some tin foil behind the shelves and bookcases where the router sits. I use 5GHz for my main network, and it has a 62 character password (I only need to set it up only once, so it is not inconvenient). That router feeds a secondary router that I use for guest network and IOT devices. The secondary network is bandwidth and ip address limited (allows only 3 unregistered devices). It is also firewalled off the main network.

I didn't think a Faraday cage is warranted, but I do encrypt sensitive data.
