The Fujitsu manuals are really good. Like you say, it's not often that you see that level of detail in the ARM world - or, frankly, the non-x86 world in general. From my prehistory as a Hyperscan developer back in the days before the Intel acquisition and the x86-only open source port, I have a lot of experience chasing around vendors for latency/throughput/opt-guide material. Most of it was non-public and/or hopelessly incomplete. I salute your dedication to nerd-sniping. I need my creature comforts these days too much to spend days out there in the nerd-ghillie-suit waiting for that one perfect nerd-shot. That may be stretching the analogy hopelessly, but working with just architecture manuals and simulators is tough. I am more aiming for nerd-artillery ("flatten the entire battlefield") these days: as my powers wane, I'm hoping that my superoptimizer picks up the slack. Despite my skepticism about SVE, I will retarget the superoptimizer to generate SVE/SVE2.
