It seems like your entire decision comes down to the BSD userland? Which is the exact same as you’d get in, eg, FreeBSD. If you’re that wound up about it, why not ‘brew install coreutils’ and then add the optional command in the install errata notes to your zshrc, giving you the gnu userland permanently? (The shell is probably low-key another point of friction. Zsh and csh do feel older compared to bash. Oh my zsh helps a lot imo, but you can also just use bash too.)
