>100% free
You know about the existence of POWER9, so I don't want to be very pedantic; but, of course, there is no such thing as "100% free" on x86, even on librebooted machines. They still run CPU microcode, EC firmware and other non-free components. Here's some excellent research done on the matter by the developers of open-source firmware projects and other security researchers:
https://osresearch.net/Heads-threat-model/
https://osboot.org/faq.html
https://blog.invisiblethings.org/papers/2015/x86_harmful.pdf
The real solution would be indeed switching to an actually free as in freedom architecture like RISC-V or OpenPOWER. But I realize they are not really consumer-grade options, currently.

>unremovable ime blobs
Again, I don't want to be pedantic and you might already know about this, but although some machines do not fully remove Intel ME (like the X230 and other Ivy Bridge machines), I would argue they still neuter it to the point it's basically innocuous, since main components like the kernel and the network stack still get removed by me_cleaner. However, you should listen to the actual developer's words: https://github.com/corna/me_cleaner/wiki/How-does-it-work%3F
