		 ', ',

## trimmed out other lines for length

		switch_if(
			$publisher=='Archive of Our Own', urls_from_identifiers('ao3:' & select($identifiers, 'ao3'), 1),
			$publisher=='FanFiction.net', urls_from_identifiers('ffnet:' & select($identifiers, 'ffnet'), 1),
			''
		), ',',

		switch_if(
			!$publisher=='Archive of Our Own', urls_from_identifiers('ao3:' & select($identifiers, 'ao3'), 1),
			!$publisher=='FanFiction.net', urls_from_identifiers('ffnet:' & select($identifiers, 'ffnet'), 1),
			''
		), ',',

	)

This gets the result I want:
- if both ids are available, both are listed
- If publisher is Archive of Our Own, the ao3 link appears first.
- If publisher is FanFiction.net, the ffnet link appears first.

But is this the best way to do this?

You shouldn't need to duplicate the switch_if. I haven't tried to run this template but it should produce what you want:

program:
	list_join(
		 ', ',

## trimmed out other lines for length

		if $publisher=='Archive of Our Own' then urls_from_identifiers('ao3:' & select($identifiers, 'ao3'), 1) fi,
		 ', ',

		if !$publisher=='FanFiction.net' then  urls_from_identifiers('ffnet:' & select($identifiers, 'ffnet'), 1) fi,
		 ',',
	)
