Buddha's advice regarding meditation practice

It seems clear to me that the Buddha's only intention throughout his life (after becoming a Buddha) was to help as many people as possible to reach Nibbana. But I think he gives different meditation instructions to different people with regard to the path to reach Nibbana. I would like to know what kind of meditation practice did the Buddha advise the monks to do, in contrast to lay people. Did he always teach them to practise Samatha first, and then Vipassana? Did he ever teach anyone to practice the 'dry insight' path, without ever doing Samatha meditation? As a general rule, were there any differences in the meditation practice that he advised between monks and lay people? I am aware that the Buddha prescribed basic morality for all, and that some people would reach Nibbana at the same time as hearing him speak about some aspect of Dhamma without doing any kind of formal meditation practice. But I am only interested in the kind of meditation practices that he taught. Please add references where the Buddha advises on meditation practice.
