What is the difference between sujet and thème?

le sujet du débatthe subject of the debate

Focus: what the discussion is about

le sujet de + discussion / article

Le sujet du débat est la place du vélo en ville.
The debate is about the place of cycling in the city.

le thème du débatthe theme or topic of the debate

Focus: the focus organising the discussion

le thème de + debate / workshop

Le thème du débat est la place du vélo en ville.
The debate’s topic is the place of cycling in the city.

Both sentences work. The difference becomes more useful when you compare a particular event with a broader idea. A report can be about the opening of a library; a story about that opening can explore friendship, independence or belonging.
