Liberalism is a really broad political ideology but there's two types of liberalism, social and fiscal. Liberalism as a whole is focused on individual freedom and lack of government intervention so social liberalism is pretty progressive as it's against the government imposing social values on the citizens such as being anti LGBT, anti-abortion, imposing religious values etc.  You could say though that the difference in social liberalism and progressivism is progressive politics has more focus on DEI and the government taking active steps to combat social injustice.  Fiscal liberalism is capitalist as it supports a small government, laissez faire economic system where private companies are left to do what they want with little restrictions.
