I have DietPi running on a Raspberry pi Zero W (armv6l), which is a system that's supported by barely any distros nowadays.

It was easy to preseed, has the absolute bare minimum amount of processes running, and is altogether a fantastic distro. Highly recommended.

For what it's worth, plain Debian runs fine on those as well, most easily via https://raspi.debian.net/tested-images/
