I’m going to comment on the homebrew part because well that’s your tastes but I personally think it’s the worst package manager I have ever used and is not really a port system so opinions do vary here.

> I have to learn the replacement from ifconfig

MacOs switched to networksetup and ipconfig a long time ago. Ifconfig is not recommended so the situation is exactly the same than on Linux here.

> launchd IMHO is way better than init.d and systemd

Systemd is basically a more complete and better designed launchd. Having used both I have trouble thinking of anything launchd does better.

> the command line diskutil and other additions still feel like its more Unix like

Diskutil is a MacOS only tool. I’m a bit lost about what your argument is here.

Linux still use fdisk and dedicated tools to create file systems exactly like on FreeBSD or any other Unix. It’s MacOs doing its own thing here.

Thank you for correcting me I appreciate it I will use those new commands.
