Honestly if you are thinking about your phone listening to you then you probably should look into running something other than stock. (You are not most people)
It depends. What I would do if you are interested is buy a cheap damaged phone that is still usable and then flash it with Lineage. From there you can break things without causing issues on your main device.
Good for you, never mind then. However, most people run preinstalled OS, so I just assumed you also would.

Good point. How complicated is it to install lineage OS on a Fairphone while also keeping/transferring my contacts?

Interesting, thank you!
