would you mind elaborating on the benefits? like what does one actually gain in a real-world scenario by having the software tuned to a specific machine?

disk space aside, given the sheer amount of packages that come with a distro, are we talking about 30% less CPU and RAM usage (give or take), or is it more like squeezing out the last 5% of possible optimization?

Closer to thr 5% . Between the intermediate code and final code writing there is an optimization stage. The compiler can reduce redundant code and adjust based on machine. i.e. my understanding is an old 4700 can have different instruction sets available than the latest intel.gen chip features. Rather than compile for generic x86 the optimization phase can tailor to the machine's hardware. The benefits are like car tuning, at some point you only get marginal gains. But if squeezing out every drop of performance and reducing bytes is your thing then the wasted compiling time may not been seen as waste.
