I recommend running fiber, but my old day job was in wired networking at
a big chip manufacturer. I think fiber parts are getting a lot cheaper
lately.

I recommend replacing Ethernet cables with wifi when possible, both for
noise and rfi problems, as well as reducing the chance of lightning damage.

Although I don't have an amp, and ran my K3 barefoot, and run my K4D
barefoot as well, I do have a 100 foot CAT5E cable running into the shack
from the other end of the house, through the attic (there being no basement
here in south Florida!). Initially, I was seeing a fair amount of noise
from it, and was able to quench it by winding a couple of turns around a
small clamp-on choke.
That doesn't seem to affect the network performance, so I can reliably run
it at 400MBit/second, and it seems to clean up whatever other noise it's
picking up from nearby homes (most are on small lots of about 1/5 acre) and
the condominium complex next door. I still have some strange noise from
other sources coming in from the antenna, and the HVAC's air handler is
very noisy, particularly on 30m through 15m, but I know it's not the
twisted-pair Ethernet line. My CAT5E cable plugs into a small AC-powered
router, and feeds my Mac, the K4D, as well as a laptop occasionally.

One culprit I can think of is a 100-foot Ethernet cable between my
station and my FIOS router. I have bought a shielded replacement but
have not yet installed it. After reading some of the recent commentary
about so-called "shielded" cables, I'm wondering if this is worth doing.
Any suggestions, either K-3-specific or more general, would be much
appreciated.
