I did a clean install of Noetic in Ubuntu 20.04 on WSL 2. This installs Gazebo 11, but Gazebo does not run when I type:
gazebo
Other X11 utilities like xeyes work fine in WSL, so the X-Server and DISPLAY are fine. I also went to the official Gazebo page: http://gazebosim.org/tutorials?tut=install_ubuntu&cat=install, and followed those directions, which just confirmed that I already have the latest version of Gazebo.
Has anyone gotten Gazebo working with Noetic in WSL2?

Shouldn't the question be: "has anyone gotten Gazebo (in Noetic) working on WSL2"?
If Gazebo didn't work in Noetic, I assume ROS Answers would be full of posts about it not working.

I would have thought so. But I would also expect that after uninstalling Noetic and Gazebo, and doing a clean install it would just work, but it doesn't.

I'm not sure what you mean by this.
Gazebo is a rather heavy 3D application making use of OpenGL. Regular X applications are not. Comparing xeyes to Gazebo isn't really useful, as the former doesn't come close to the complexity in the graphics pipeline of the latter.

Ah, I figured it out. I had forgotten to set: export LIBGL_ALWAYS_INDIRECT=0
When I ran in Melodic, it gave me an error if I forgot this, but Noetic doesn't give an error, it just doesn't run. It was helpful discussing this with you, @gvdhoom, thanks!
