I'd like to replace my stock enclosed air intake, but I'm not seeing much online for options on a Short Ram or Cold Air. Anyone know what engine parts match the 300h?

A cold air intake comes standard on all cars. Are you just looking to get more noise when you floor it?

I'm looking to get rid of the enclosed air box style intake. Hoping it will make the air flow more efficient. Not too worried about noise, mainly performance.

So looks is your goal. A different CAI will not improve performance on the 4cyl in the 300h.

Not trying to be a wise-***, but if you wanted performance why buy a 300H?
Even the standard 350 is borderline on performance, it is, after all, a 4door family passenger car.
We love our '16 350 but it is our long distance hauler for traveling in comfort - when on the road we put it in "sport" mode which tightens things up just enough to make it a nice cruiser for traveling at 80.

I'm not looking for performance, in the sense of building a race car. I'm simply looking to build a more efficient vehicle by upgrading stock parts that make sense. And by efficient I mean more MPG and things like that. I will not be upgrading major engine parts, but if a certain intake and exhaust will improve performance and MPG, then it would be fun to customize it and get more efficiency.

A cold air intake is not more efficient than the stock system. Dumping more air requires more fuel to burn the mixture.

Too big of an exhaust pipe can lead to less back pressure making it also less efficient.
