I don't play ENHC,but I think the only plays it affects are ones that require you to put extra money at risk. As you are neither splitting or doubling your 16,the fact that the dealer doesn't take the card until later seems meaningless.As the dealer is very likely to make a hand with a first card Ace,I'd certainly hit it.
But this is an opinion,not a fact.
