$\begingroup$ Quite excessive use of /@ inside Pick. Unleash the full power and beauty of Pick by taking advantage of the Listable attribute: Pick[var, StringTake[ToString /@ var, 1], "e"] and Pick[var, StringContainsQ[ToString /@ var, "e" ~~ _]]. $\endgroup$

$\begingroup$ Note that StringContainsQ["aer", "e" ~~ _] returns True what isn't what you want. The correct test is StringMatchQ["aer", "e" ~~ ___]. $\endgroup$

$\begingroup$ @ubpdqn I've edited the answer and replaced StringContainsQ with correct method which uses StringMatchQ. $\endgroup$
