"Beginners" should be taught what is honest & true (rather than speculations & superstitions).
For example, the Maha-Mangala Sutta lists the many blessings of the Buddha-Dhamma, without mentioning 're-birth' or 're-incarnation'.
Following the guidance given in the Pali scriptures, beginners can be taught the following dependent upon their needs & aspirations:
(1) The many benefits of morality (non-harming), which include the preservation of psychological 'normalcy', integrity, self-respect, trustworthiness, social relationships & freedom from remorse & regret.
(2) The benefits of giving/generosity, which include happiness, beauty, strength & self-respect.
(3) The dangers of sensuality & extreme behaviours (such as gambling, intoxicants, etc), which include addiction, loss of freedom, breakdown of relationships, loss of wealth, bad health, etc.
(4) The benefits of the Brahmavihara, here.
(5) The benefits of concentration meditation, particularly how it brings a free here-&-now pleasure/happiness that is superior to worldly/sensual happiness.
(6) The benefits of wisdom, in ending sorrow & suffering & guiding life safely.
The Blessed One discoursed to him a graduated sermon, that is to say, he spoke on the subjects of liberality, virtue, the heavens, on the
evil consequences, the vanity and the depravity of sensual pleasures,
and on the advantages of renunciation.
When the Blessed One perceived that the mind of Upāli, the householder, was prepared, pliant, free from obstacles, elevated and
lucid, then he revealed to him that exalted doctrine of the Buddhas,
viz. Suffering, its Cause, its Ceasing and the Path.
