Unfortunately the OEM spot is the "best" solution due to the sharply rounded front of our cars. Not much real estate off to the sides to work with.
One option is to install the Pierce Motorsports tow hook mount and somehow tie into that with a plate mount kit. You'd probably have to fab something custom but it would work.
Whatever you do, don't mount it in front of the intercooler (like some do. The Sto-and-Sho is a good example of what not to do. https://stonsho.com/) and I'd be hesitant to mount behind the honeycomb because it would be blocking airflow to the radiator/condenser.
This thing looks pretty rubbish and doesn't really solve the "problem" of mounting the plate front & center, but it is an option of sorts: https://www.amazon.com/dp/B08RN7NPVX The price is ludicrous.
Some more discussion here, same conclusions. https://www.fiestastforum.com/threads/front-side-license-plate-mount.3140/
