I have a standard plastic water valve in a rental property that is leaking
past the stem.
I see where it may have been possible to tighten the packing nut, but there
are ribs on the outside of the valve, parallel with the stem, now preventing
it from being tightend any further. Are plastic valves repairable? If I
remove the circular handle, and then back off and slip the the packing nut
over the stem, what is inside a plastic valve? Does it seal by using an
o-ring that slips over the stem and is compressed by the packing nut? I
assume it doesn't contain regular packing material or what might be found in
a brass valve.

What I would try is to shut the water off, remove the packing nut, and
see whats inside. Repair/replace if possible. If you can find an
identical new valve, then you could swap out the stem/handle to the old
valve body.
