It seems that simulators running iOS 13.x and some specific devices runs in "Rosetta"-mode rather than "Apple Silicon". These devices are hidden by default in the latest Xcode version on macs running with Apple Silicon.
To be able to use these run destinations in Xcode, open the Product menu -> Destination -> Destination Architectures -> Select "Show Both"..
Also note that some devices will remain hidden even after enabling this option, for those you'll have to navigate to Window -> Devices and Simulators -> Simulators and then select the device that's hidden. Then select "Always" on the "Show run destination" option.
