I can't comment on your options in Google, but one or two things to consider ...
It depends on what information you intend to capture. Hubitat maintain a list of devices they have tested and consider compatible with the hub, linked at the top of the Devices page. Plus there is a Wiki here on the Community that we can maintain for devices that have Community developed drivers / apps (not developed or maintained by Hubitat).
These are both primarily lists of devices. If you want to record more information, then you may need something else, like what you were describing.
Also, depending how you would like to interrogate / search through the devices, then a Wiki-style page may not be suitable.
