EDIT: I meant for this to be in the "Discovery episodes to watch in preparation for Strange New Worlds" thread. I had both threads up in separate tabs and I got them mixed up. I'm an idiot. However, oddly, I still think 60-70% of what I wrote still works here - STW seems to be taking The Orville Approach. But apologies, neverthless. I need to pay more attention and/or stop doing this stuff at work.
Honestly, I think just watching Season 2 is your best bet. If you just watch the Pike centric episodes, you'll miss a lot of the Spock stuff, and vice versa.
In that Variety article, Goldsman does say Strange New Worlds will be episodic like old school Trek BUT with character development. Meaning the experiences and choices the characters make will carry over the the following episodes. If they're doing that, then there's no reason not to expect the events of Disco Season 2 to effect where Pike and Spock are mentally when we first join them in Strange New Worlds. Pike knows his ultimate fate, how does he deal with that? How does Spock handle losing Michael?
And as others have pointed out, don't skip the Short Treks. I can't help but think Q&A, The Trouble With Edward and Ask Not were kind of a pseudo pilot for Strange New Worlds.
