Most 2 sided debates fall into these two types.

They are rarely 100% Value Debates or 100% Policy Debates

Value debate
A value debate is one that is about a specific value, such as individual rights or Justice. In a value debate the teams are expected to argue the importance of concepts and not specifically a policy. Reference Wikipedia

A value may be universal and apply to the past, present and future.

Examples:
Science and religion can successfully coexist in a modern society.
University education is a waste of time and money.

Policy Debate
Policy motions are usually concerned with the current situation and how they could be changed. They want to either:
A Introduce a new situation which does not currently exist in the status quo: ’This house would give every citizen a universal basic income’ is an example of this. No country in the world has a universal basic income at the moment, so this would be an innovation, something which does not exist currently.

or:

B Adapt the status quo: ‘This house would introduce a 20 mph speed limit in all built up areas’ is an example of this. Speed limits already exist, and are part of the status quo; the proposal is to change the status quo by making them stricter. Policy motions are about either innovating or changing for the future.
