The new 2024 Subaru Crosstrek calls for 0w-16.

Mostly annoyance that it is one more part to stock. Apparently there were availability issues getting it for a while from Toyota.
If you're curious what the engineers that built the engine would recommend, try finding Subaru Japan's recommendation. Still, not directly from the "engineers" but closer than an SoA recommendation.
I would expect them to allow a range of oil grades which is the case for most models. The FA24DIT has always only specced 0W-20 in the U.S., even in the new WRX, but in Japan the WRX owner's manual lists 0W-20, 5W-30, and Euro 0W-30.
I tried finding the JDM Crosstek/XV manual but it looks like they've recently changed the manuals on-line and I couldn't find the info.
It's not miles per gallon of gas, it's miles per quarter of oil.As if the FB engines did not burn enough oil already...

Who cares how much R&D money the OEMs have spent, you shouldn’t fall for their watered down COFFEE conspiracies and should run the thickest and most safest oil you can find.
As a New Hampshire resident, this state is full of Subarus.....and that video is so painfully accurate, I don't consider it humor. That video is borderline a documentary.
Some Subaru models with FA or FB engines have oil coolers that work pretty well (though maybe just the turbo FA models?), and some models have oil temperature sensors that can help determine if a thicker grade of oil is really warranted.
I've been wondering if there were any real design changes made for the FA24 that were meant to facilitate the use of a thinner grade, or if they just decided to test and validate the thinner oil with the engine design largely unchanged. The journal bearing specs seem unchanged between the FA20 and FA24, with the turbo FA20 spec'ing 5W-30. Not sure if there are any other significant design changes to the oil pump, oil cooler, or pistons or anything that would affect the appropriate oil grade. I haven't been able find a service manual for any model with an FA24.
I had a '19 XV and used 5W-30,
I have an '18 Forester with the FA-20. I plan on going with 0W-40 for it and also going with 0W-40 for my '22 Forester which calls for 0W-20. They can put their thin oils where the sun doesn't shine.

Research and development is involved when choosing an oil grade?
Ford must have missed that memo with the first gen ecoboost engines that originally specd a 5w20 and went back to a 5w30.
Ford also recently went from 5W-20 to 5W-30 on the 5.0L Coyote V8. Nothing to do with "bearing clearances" which have basically been the same for decades on engines, but more to do with increasing engine protection, while loosing CAFE credits.
