So this is a non-shielded cable. Is it direct burial? Or in conduit?
Had several customers over the years with a similar scenario. Conduit
full of water. Penetrated the cable. Very ungood. Can't even get it to
run at 10/half without errors. Replace it with a PTP link.

Any time you separate transmitters & receivers by any distance, you
have the "potential" to have grounds at different potentials (I did
not really intend that pun, but it works).
So, often, it is a wise choice to ground at one end, but not the
other. This retains most of the shielding without causing current on
the ground leg(s).

Different grounds can cause a problem. Are the house and barn on
different meters?

The customer has a 100' run of Ethernet cable from the house to the
barn, and a switch in the barn. I'm wondering if there might be an
issue with different power sources, possibly different grounds
between the router and the switch. The issues are intermittent
enough that I can't ask for them to just disconnect their barn as it
is used for work.
If I install an unpowered gigabit PoE injector in-line with that
100' run, will that eliminate any issues with different power or
different grounds between different buildings since the buildings
would be on separate sides of the magnetics, or do I need better
separation?
