This is my third Jeep I-6 but the only one that has had this tendency. It was neglected by the PO and the inside of the engine is grungy even though it runs like a top. I wonder if that might have something to do with it.
I bought a Napa Gold with the intent of using it for the cold months as it had a silicone ADBV, thread end bypass and is a stoutly made filter. The ADBV on it won't even seal on the blow back test so I'm mighty disappointed and won't be using it.
I'm pondering trying a Motorcraft FL-400S, it's not a spec filter for my Jeep but it will fit just fine and has the features I hope will get this rattle to go away.
Any experiences with a particular filter that has done a good job of eliminatiing rattle?
For reference, filters I've already tried that will all produce intermittent rattle include: Puro Classic, PureOne, Motorcraft FL-1A, Fram Extended Guard XG8A, STP S8A, Baldwin B2 and the Wix Napa Gold I refuse to use.
I thought I'd post an update. I am pleased to report the FL-400S did indeed fix my start up rattle. I had gotten to a point I didn't think any filter would, it was my last attempt. Well it worked, and I gave it a good test too.

Almost a month and a thousand miles, colder weather than ever, several "perfect storm" scenarios where the Jeep sat for nearly 48 hours in cold weather. No rattle, not even once! And this from a vehicle that had been making racket every third start or so before the switch.
All I changed was the filter and extended my OCI a month. It worked hurrah!
Motorcraft FL-400S for the win!
