Smart Three-Way Switch Recommendations
These all require a smart home hub with Zigbee capabilities. I prefer to use Home Assistant with this Zigbee USB stick (which also does Z-Wave). There aren’t a lot of choices for Zigbee switches.
The Enbrighten switch recommended below supports a three-way configuration, but you must buy their add-on switch to pair with it. You can also use the Enbrighten dimmer in a three-way configuration.
