Yes form_id and inbound_form_id are interchangable when it comes to rules and targeting Inbound Forms. If you ever use Ninja Forms 3, Gravity Forms, or Contact Form 7 then you’ll just target form_id.
Sometimes there’s oddities. If you ever do not see something in a filter you expect to see, head over to whatever trigger event the trigger is related to and perform a test action, and then head back to the rule and see what the dropdown shows. It always shows a capture of the last bit of data that moved through it, plus whatever you have stored into memory.
