I’m wondering if they’re even zigbee or some other proprietary Xiaomi wireless technology? I had assumed every Xiaomi sensor was zigbee, but maybe I"m wrong?

Only the “Xiaomi Smart Wireless Switch” you linked to is a ZigBee device. It’s also known as the “original” Xiaomi Button, and you can find my updated device handler to help it to work with a SmartThings v2 or v3 hub here:

[UPDATE] “Original” Xiaomi Button DTH v1.3 For Xiaomi’s round button, model WXKG01LM [button] This release adds support for previously hidden functionality that has been “revealed” with firmware version 25.26. Because Hub Firmware 25.26 is required, this new DTH should only be used by SmartThings Hub v2 and v3 users. Let me repeat that: NOTE: This updated DTH only works with Hub Firmware 25.26 or higher, which is currently only available for SmartThings v2 or v3 Hubs The updated Xiaomi Button DTH code can be found here. NOTE: After updating to the new DTH, open the preference settings for your button in the SmartThings “Classic” Mobile App and then press “Save”.

The Yeelight Smart Dimmer switch, however, is a Bluetooth device, or at least the description in your link claims as such.

The only way to get a Bluetooth device working with SmartThings is to use some kind of “bridge” solution between the manufacturer’s proprietary interface and the SmartThings hub. There is a solution that allows linking a Xiaomi Gateway hub with SmartThings, but it doesn’t list support for the Yeelight Smart Dimmer switch, so I would recommend asking the author about it here:
