And what about molecule size? I have the impression that hydrogen molecules are
somewhat of an escape artist, so helium should be worse. Or is that only when it
is stored in gas state?

Hydrogen is only an escape artist when it isn't combined with
something, and it combines with things with great alacrity, unlike
helium. But helium is obviously more massive and easier to hold on to
in itself.
