Normally, MacPorts X11 is only running if you tell it to by opening /Applications/MacPorts/X11.app. You can configure the system to automatically open MacPorts X11. But if you did that, you'd know the commands you entered to do that, and you could follow similar steps to switch back to Apple's/Xquartz's.

Installing xinit will install a LaunchAgent to make it the default.

Right, because your DISPLAY is still set to the MacPorts one.  You likely failed to also uninstall xinit or need to just logout and back in to update DISPLAY.

Use a DISPLAY environment variable corresponding to that server.
