Probably a dumb question, but is there a reason there is no
`cp` and no `mv` in `s6-portable-utils`?

 Because reimplementing a full POSIX utility suite isn't a goal.
There are already a lot of those you can choose from (coreutils,
busybox, toybox, sbase+ubase, etc.)

 That said, if you don't have a cp program available, there's
s6-hiercopy in s6-portable-utils.

What’s the recommended way of copying and moving files?

 It really depends on your environment. I wrote s6-hiercopy for
stripped-bare environments (think initramfs). On a normal system
chances are you have POSIX utilities available, and cp/mv should
work fine. :)
