If you're worried about tying all of your stuff to a giant amoral company, then your only realistic option right now is a stock Android phone with a de-Googled Lineage OS ROM, using the F-Droid store for software.

A legislative effort to partially debundle hardware from the exclusive control of a single company could be very helpful in mitigating the situation you describe.
