So I went ahead and it works! At first it did 3840x2160 only at 30 Hz,
but after rebooting it now runs at 60 Hz, at least according to xrandr
(see below).
Is there a way to independently verify the refresh rate? Unfortunately
the monitor doesn't display it.
For the record, this is an Asus

I went ahead and bought a Plugable USB-C to DisplayPort cable to confirm
that there are no issues. I unplugged my mDP to DP cable from the
NUC6i7KYK and the HP Z27s

It should work fine because the USB-C ports have DisplayPort signaling
built-in and I would not expect any issues.

The spec indeed says it can only do 30Hz over HDMI, but 60Hz over DP.
So thanks for pointing this out, you saved me from buying the wrong
cable.

Can OpenBSD drive a 4k display on integrated Intel graphics via HDMI
these days? Specifically, I'm hoping to connect it to my laptop's
"Intel HD Graphics 620" (Kaby Lake) via a single HDMI cable (which
would go into a USB-C-to-HDMI adapter).
