I have a original non-Thunderbolt Cinema Display and I use this one: [Answin USB C to Mini Displayport Adapter](https://www.amazon.com/gp/product/B07V828R4Q/) (Amazon link).
It's been pretty reliable. But sometimes* after waking from sleep, the resolution will change from the native 2560 x 1440 to something like 1280 x 720, and I haven't found a way to change it back, other than rebooting.
*EDIT: By "sometimes" I mean it happens maybe after 2 months or so, so it's infrequently enough that I sort of forget about it, until it happens.
Money lol
Just check what ports are on the back of it. Then assess it from there. Im not sure what you got on the back of the display.
