I’ve been rolling with Allen and Murray, but I picked up Foles as I plan to drop Allen after this week. Even that Balt matchup doesn’t seem like a good one if they have their full secondary healthy. I don’t trust him against good defenses since his floor is pretty low.
Out of the options you listed, Wentz seems like the safer option if he can get some healthy receivers. You can make an argument for any of them though.
