In looking through a box of miscellaneous cables, I found one that was
USB-A at one end and male Ethernet at the other.

What would this be used for?

Thanks.

Are you saying there is no circuit board in the middle? I can't say
I've seen one like that.

Yes, I am.

I don't know about this cable in particular. There are devices that can
plug into either USB or other devices using the same port. I suppose
this could be connecting to a device that is like that and uses an RJ-11
connector.

Probably an APC Parachute cable. If you install Parachute on your computer,
APC uses that kind of cable to signal the software when it's time to start
an orderly shutdown of your computer and applications in the event of a
power failure.

What do you plug it into exactly? Is there a special board in the PC?
Or it uses USB in the PC and the RJ-45 end is for the UPS?

Yes, USB-A at PC end and RJ45 at UPS end. Some APC UPS's have a USB-B jack
on them and some have a RJ45 ... I'm not sure why the difference.

I've never used the feature myself, but just recall that every time I
bought a APC UPS it came with one of those cables thrown in the box.

(Oops, the feature is called PowerChute, not Parachute. I was remembering
the red parachute logo APC used for their software.)

On some earlier UPS they had USB at the PC end and 9-pin sub-D
("serial") at the UPS end. The signalling was NOT RS-232 though. It
can be confusing when connectors that have a "usual" role
(sub-D/serial, RJ-45, etc) are used in a non-usual way, and can cause
confusion at least if not actual risk.
