Economic policy is a huge area. I don't know if you can get a succinct answer on the whole lot.
This Marketwatch article for example, implies that there are significant differences, but doesn't provide any solid details on those differences.
A potential 2020 election showdown between President Donald Trump and Democratic candidate Elizabeth Warren would undoubtedly be touted as a clash of ideological extremes, but when it comes to economic policy, there is one area where there’s little daylight between the candidates.
This area where their policies are similar is apparently the belief that the US Dollar is too strong.
But both Trump and Warren contend an overly strong dollar hurts U.S. competitiveness.
The Washington Post contrasts the approach Trump and Warren take to international Trade Deals. In broad terms both are sceptical of traditional (republican style) free trade deals that focus on removing trade barriers.
The post characterises the differences in approach as Trump being supportive of tariffs to protect industry and Warren supportive of Labour and Environmental protections, for much the same end. Protection of jobs within the US, by lowering competitive advantages of cheap labour markets.
Trump
Appeal to voters who have been hurt by globalization by criticizing free-trade agreements and supporting trade barriers. But he appears more willing than most Democrats to actually impose tariffs and other trade barriers.
Warren
...calling for stronger protections for labor and the environment in U.S. trade agreements with other countries. Our research suggests this approach is popular with the U.S. public. Americans like free-trade deals, but they want the deals to come with protections.
