I was one of those AWS people that worked with Financial Services customers.

We (at least my team) were always pushing for a minimum of modernization when architecting migration projects - even a simple move to containers, managed by whatever orchestrator they want to run. It helps enormously on costs at least by just taking off so many overhead and overprovisioned VMs from the roster of migration candidates.

More often than not, the customer will refuse that and opt for lift + shift. It's either too hard, they don't have the resources or time, etc.

Yep I did a (tiny small by your scale) lift and shift+ - basically take a thing that ran as a regular process with a database attached, and containerised (and pen tested, but that's another story) the thing and plugged it into a cloud-managed database. It worked great.
