While your point about Docker’s primary purpose is valid, containerization is commonly used for security isolation as well. With proper configuration, it can be very useful towards this end.

Can you suggest any preferred alternative methods of isolation that offer similar efficacy and ease of use for quickly running complete software systems made by an unknown/untrusted actor?

It can. I think it's fair to assume that the standard developer setup to let them be productive is not this proper configuration.

No. It's a hard problem! If it was easily solved we wouldn't be seeing all this development surrounding e.g. WebAssembly

Bubblewrap, Firejail, SELinux, etc
