I am new to iOS reverse engineering and I am trying to download an iOS binary from my phone to my mac to run in the Xcode emulator or examine with ida pro and possibly debug with gdb. Are there any good places to look for doing this?

Another way is to use ssh to locate the app package and copy it back to your computer with scp command.
