I am 100% with @MK24.
I have multiple WG tunnels on my router to different locations.
You can make multiple SSIDs and with PBR you assign a specific SSID to a specific tunnel so that you can switch locations by switching SSIDs.
You can easily extend this to a secondary router running as Dumb Access Point Bridged AP over ethernet: https://openwrt.org/docs/guide-user/network/wifi/wifiextenders/bridgedap
