Thank you for your question! What research design to use will depend on your specific study question, your study population, your methodology, and whether it is a prospective, retrospective, or intervention-based work. Several sets of recommendations exist for the optimal research design of a study; the EQUATOR network (https://www.equator-network.org/reporting-guidelines-study-design/experimental-studies/?post_type=eq_guidelines%26eq_guidel) provides a comprehensive overview of these as well as a tool to recommend the appropriate reporting guidelines. Overall, the core basis for this decision should be “what would best help me directly address the research question”; generally, novelty in methodology is not a necessity or an expectation so long as a unique contribution is made to the body of knowledge. For your specific query, both longitudinal and cross-sectional studies exist on the role of sleep in adolescence from various aspects, so you do retain the freedom to choose what best fits the needs of your work. I hope this is helpful!
