You're right there's really no info out there on the Crosstrek Hybrid specifically. There's info on Beyond Tailpipe Emissions that looks at greenhouse gas emissions for the car and upstream (meaning electric and gas production emissions).
For my area specifically, total GHG emissions is 240g CO2/mi and the tailpipe emissions alone is 151 g CO2/mi. So upstream GHG is 89 g CO2/mi. Average gasoline car in my area (again they don't compare against ICE Crosstrek) is 410 g CO2/mi.
So this at least gives you of CO2 savings per mile between the Hybrid and ICE Crosstrek (201 and 136 g CO2/mi savings). I haven't be able to locate documentation on the GHG impact of building either of these cars. Since the battery itself is 8.8 kWh, that would be the biggest contributor and probably the 2 electric motors as well. I found some information about the Prius Prime so I could use info about that. The values below in metric tonnes were pulled from Engineering Explained.
Charting this out over the first 10,000 miles, the 2 lines cross at about 1,100 miles driven. This shows that even though the Hybrid requires additional GHG to produce the vehicle, it provides a savings in GHG emissions after minimal miles.
Here's the data that went into the table:
I hope this information helps answer what you're looking for.

- 151g CO2/mi is what they say is listed on the window sticker for my car (I could go confirm this later)
- They say the average gas vehicle data comes from a car with a fuel economy of 27 mpg. They then add a factor of 1.25 to account for emissions from the production and transportation of gasoline.
- For a 2019 ICE Crosstrek, I found on the same website that the 6-speed produces 353 g CO2/mi and the CVT produces 301 g CO2/mi (tailpipe emissions). If I take the factor to account for production/transportation of gasoline, these become 441 and 376 g CO2/mi, respectively.
