I mostly work in Python and find the PEP and documentation hard to get through without a strong C background. What resources or exercises would make free-threaded Python easier to learn?
Where should I start learning about free-threaded Python without much C?

Start with why free-threaded Python exists rather than how the interpreter implements it. A high-level overview of PEP 703 can give you the motivation without making you follow every C-level detail.
Then write a few small threaded programs and compare them on a regular interpreter and a free-threaded build. Having a concrete example to think about can make the documentation much less abstract.

PEPs aren't always great first lessons. Try conference talks or community blog posts that explain the threading model in Python terms, then go back to PEP 703 when you have a specific question. You don't need to understand all the memory management details on day one.

If you like open source, use a small project as a learning exercise. Try its tests on a free-threaded build, investigate anything surprising, and read the relevant docs as questions come up. That gives you a reason to tackle the low-level material a bit at a time.

Small examples are also handy for separating questions about program behavior from questions about performance. They are not necessarily the same thing.
