Engine has been misfiring for about 10 months (8k miles) and, it's throwing no codes. Took it in for service, they couldn't find anything. Suggested replacing spark plugs and "throttle body/fuel service." We did not do the fuel service.

We did replace all spark plugs, and the misfire disappeared for a few days - of course that could be coincidental. But it has now returned - it's intermittent, and doesn't appear to correlate with load or engine temperature. Misfire is slight and difficult for some to detect. This issue has not gotten better or worse (except for right after the new plugs).

Any thoughts?

A local shop. Not a Kia specialist or dealer.
I recommend that you have a place like Autozone read the codes and use a Dealership or Specialist shop.

But there aren't any codes. That's the strange part.
Cant be sure - don't know what code reader was used and if its capable.
