So basically the question is, do you have a specific need for tags? If yes, then the documentation of the add-on/system for which you need the tags will explain which tags are used for what purpose.
If no, then there is no need to start using them.

@lblabr

If you e.g. want use one of the following, then you need tags:

hueemulation in combination with Alexa

HomeKit

OpenHAB Cloud in combination with Amazon Alexa Skill or Google Assistant

thanks a lot!
