For almost 100€ I can just get much more capable hardware with only marginally larger footprint (both physical and power). Unless I needed the pin IO, the pi is a bad deal. And then if youre just beginning you also need a case, SD card and power supply and suddenly that pi is almost 150€ (and still running a shitty 16gb SD card), making it a horrible deal. I got my NUC, 16gb of ram and 1tb NVME for the same price (before upgrades with the default 8gb ram and 120gb nvme it was 65€), if you're planning on a miniature light weight home server setup, its just a no-brainer to not pick the pi.
And the zero doesn't have the ability to use any peripherals except for a display.
