You can build out your Zigbee network with relays (anything mains powered usually works as a router) to reach the area.
If the area is too far away (say in another building), you could setup a Zigbee to MQTT router nearby and route the messages via another network back to Home Assistant.
or your could use WiFi devices if you have enough spare capacity on your network and are well within signal range.
I’ve so far not had much luck with Matter, so for me, that is an unnecessary complication to avoid. Trying to get Matter working, I mean.
In my case I would probably use either the first or second choice, depending, but your situation may be different. My WiFi already has too many devices on it.
