Is it naive to ask why any of this is better than running your own DO droplet with Dokku? I am sure there is a better security story for CloudRun and Fly.io if you are sharing space with other apps, but if you are the only one running apps on it, is there anything to gain with using katacontainers/firecracker?

Firecracker and katacontainers (and other KVM based "containers") are valuable for multiple tenants that don't trust each other. They are less helpful if you trust what you're running.
In fact, a Fly Firecracker VM is not all that different from a DO droplet. We expose them as containers, but you could run Dokku within a Fly app and have a similar set of stuff under the covers.
