When you can ride 120 mi with no issues, the saddle works for you. Stick with it.
Don’t make too much of the Fizik fitting/rider classification thing. I test “bull” and ride an Aliante - on my road bike - and an Arione, at the opposite end of the spectrum, on my cross/gravel bike - and, go figure, both work fine for me. And I can get on saddles that look pretty darn close in size and shape to either of the two and might as well be sitting on a hatchet. If it works, stay with it.
