Naming Conventions for Teams

Hello everyone. 

I'm interested in suggestions and examples of naming conventions that companies are using for the Teams on MS Teams. I've read the "guidelines" documents. But they don't contain what I'm looking for--which is examples of what people are actually using. Here's something we're considering in my area:

Convention

Service: CLIENT - Product

Team name examples that would result from the above convention

Course: IBM - Root Cause Analysis

Coaching: PAYPAL - Leadership

Product: UNION PACIFIC - Job Skill Analysis

If you'd be willing to share examples of the naming conventions that you actually use, that would be great. I also have a question regarding the use of colons and dashes. Do you know of any reason why using symbols like these might not be the best approach.

Thanks in advance for your help and ideas!
