I think the reason you’re not seeing that kind of device is that zigbee is designed more for low-bandwidth, sporadic updates rather than continuous streams of live data like you typically expect from a probe thermometer.

Check out this device. I have several and they work well. Zigbee temperature sensor in a cabled probe.
For my own morbid curiosity, why Zigbee?
If you don't want to learn ESP Home yet, but you're ok with Wifi, here's a sensor that uses ESPHome, but is all pre-programmed and ready to go with Home Assistant. I haven't used this produce yet, but the other products from Apollo are pretty awesome.

Sounds like little project for an ESP32 with a few DS18B20. With ESPHOME they are really easy to set up.
I would do this with a home-made esphome (like other have suggested). If it has to be a commercial product, you can buy the shelly addon and attach it to any of their Z-wave 1pm products like this one for example.
The addon supports up to four temperature probes and the cables can be many metres long.
Are you looking for a long probe, or a small probe on a long cable?
Sorry, yes, small probe on a longish cable. It's for measuring temperatures on various pipes and hot water tanks to try and understand our new wood stove central heating a bit better.
The reviews aren't the best, but I did find this recently. Haven't tried it out yet.
Hey, this is exactly what I wish to accomplish.
I haven't found any readymade device either..
I have bought all the parts needed, but like you, I don't have the patience/time to put them together.
