I think the big rectangular traps have entrances
too small for well-grown snails. Whatever you use, be certain to leave a
twig or something as a ladder out of the beer otherwise ground beetles
will also drown in it -- and they're your friends, because they eat
slugs.

Here's a question - why do the traps need to be shallow - groundbeetle
level ?

I've tried just jamjars sitting on the surface, and slugs seem to be able
to climb into those ok.

Would I catch more slugs if I sank them into the ground ?

It could be that slugs are lazy, and tend to give up the ascent up the
side of the jamjar in favour of a convenient seedling, but I think
perhaps like most inverts they prefer not to be extremely exposed (as
they would be on the side of a jam jar) for too long. Try sinking some
and see?
