I ran Arch for four months recently. Even the Arch maintainers themselves describe it as a distribution building kit, not a distribution, and they're not wrong.
Using it was a fun experience and mostly very pleasant. But it made it crystal clear to me nobody should run plain Arch on a machine that would cause issues if it was suddenly lost.
If I had to choose between Arch and yubikey, I'd pick yubikey.
