The list of topics for each site should be on /help/on-topic. Questions asking which site to ask on are on-topic for the Meta sites. If you think your question might be on-topic for XX.SE, you should ask in meta.XX.SE if you are right in your assessment. If you don't have a clue which site to ask on, ask for a site recommendation at meta.SE.
