Navigating AML for cross-border digital asset transfers

Curious how others are handling AML red flags specifically with cross-border digital asset transfers. The traditional banking rails have established correspondent relationships and known FATF grey/black lists, but with crypto, it feels like the landscape is far more dynamic. What's the practical approach to identifying ultimate beneficial ownership (UBO) when assets might move through multiple non-custodial wallets across different jurisdictions before hitting an exchange? And how do you factor in the varying regulatory stances on self-hosted wallets across different regions?
