If you are looking for something more right libertarian or conservative-supported, you probably want FIRE.

If you are looking for something more consistently progressive or liberal-supported, you might want to give the EFF a try.

If you specifically care about free speech above all, you're probably right libertarian. It's fine. There's no such thing as centrism in real life politics and an individual's political alignments can vary drastically in different issues rather than line up perfectly with any specific political movement. Especially if you consider yourself apolitical or haven't really reflected on the entirety of your political beliefs and how they interact with each other (most people haven't).
