Introduction to Figma
A course that introductes the most popular tools a UI/UX desigers use would be interesting to have here at Uxcel. The format of the course may need to be different from what you currently have. Figma is the most popular one and also can be used for free for single users. The strengths / weaknesses of each tool would be interesting, as well as what tool to use for what category or stage of the design process.
