Following some of your advice I made most of the policies available from the beginning of the game.
You don't need to learn any special techs in order to set the following policies: Education, Healthcare, Mass Media, Personal Weapons, Telecommunications, Transportation and Manufacturing.

However, I kept some policies available only after research, including all new Trade policies.

Keep in mind that some policies have Ethical "backbone", like Healthcare or Education, for example, which means that

- they are not available in case you have opposing Fanatic ethos or particular Civics;
- they provide some minor attraction to a backbone ethos;
- they might provide some unhappiness to opposing Faction;
