So if I read your post correctly, the volume of starts isn't paramount and neither is the strength of the team (at least wins don't matter as long as it's not a defensive horror show), right? It's purely SV% and SO.
I'd be hesitant to pick Swayman, Oettinger, Knight and maybe even Kahkonen because they could end up being only backups (I'm aware there is potential for more, but I wouldn't want to risk a roster spot for a guy who might not even start once in a given week).
Andersen, Binnington, Jarry, Bobrovsky hold way more value in leagues that count wins, but I'm not sold on their individual skills and don't expect an excellent SV%.
Ned and Demko are good goalies, but I'm questioning the defensive support they'll be getting from their respective teams.
Markstrom seems to be have the highest floor but not the highest ceiling imo. He'll start a lot for a solid Sutter team. Not much that can go too wrong here.
However the guy I like best is Petersen. That must be a surprise for some reading this, but his individual SV% has always been very good, his team added two excellent defensive fwds which should limit high danger chances against him and is generally on a good trajectory. Finally he's still young enough to be valueable for many more years.
This leaves Merzlikins as my wild card. CMB looks mediocre on paper, but they're solid defensively. Elvis is a very talented G and he'll play with a chip on his shoulder: it's a contract year for him, he'd want to set himself apart from Korpisalo under a new coach and he'll play for his late friend Kivlenieks. He hasn't been the most consistent of all Gs, but if he can start more regularly his SV% (which has always been very solid on average) could be even better.
