> I am just not sure it is worth leaving the Linux ecosystem. What if I want to run a Docker container? Do I have to trust random people for ports of software that runs natively on Linux, or port it myself?

You already trust random people in linux, you have to trust even more random and more people when you run docker.

Ports are quite large collection already. If you port yourself it's either up to 20 minutes plus compilation time or major nightmare. More and more software today assumes you run on linux only.

I think FreeBSD is great for setup and forget. If you have to interact with it regularly it's not worth it. Definitely not worth it for desktop.
