I think I got it to a happy place.
If you're not familiar with the MSFS file structure or have never done this before, I discourage it, but if you have you can replace these lines at the end of your warrior flight model file
flaps-position.0 = 0, -1, 1, 1, 1, 0, 0
flaps-position.1 = 10, -1, 1, 1, 1, 0, -0.2
flaps-position.2 = 25, -1, 1, 1, 1, 0, -0.3
flaps-position.3 = 40, -1, 1, 1, 1, 0, -0.4
There's no impact to lift or overall handling of the plane other than to give the expected mild nose-up with flaps going down.
