Any advice for these Costco NY Strips? (First timer)

My husband and I are upper medium rare to medium people so I was thinking 135°F for 2 hours—salt, pepper, and aromatics in the bag. Then finish with a quick 30 second–2 minute sear in the cast iron with some butter and let rest for ten minutes. Thoughts?
