Prolia may be a far better medication for you than any other. Your physician knows your medical history and what vulnerabilities to any of these medications engender. Together you have decided on Prolia. I't isn't of value to you for me to try and enter that decision.
If you were (still) choosing between an anabolic and an antiresorptive, I would advocate for the anabolic. I see structural advantage in integrative bone.
As for proof, in all the research--microscopic bone studies, mechanism of action studies, associative studies, the "proof" is patient experience. You will be the proof of Prolia's superior value to your bones.
Bless your choice with the best luck.
