Welcome and thank you for reaching out to our community.
While your current approach of short and simple labels is acceptable for now, especially if the meaning remains clear as your dataset grows, I favor the latter suggestion. Descriptive labels offer several advantages: reduced confusion for multiple users, improved maintainability, and less chance of misinterpretation. The downsides are increased length and the need for consistent naming.
I hope I was able to provide you with useful insights.
