I know of no evidence that children born of middle-aged parents are particularly advantaged or disadvantaged. The "famous" risk is of course Downs Syndrome whose incidence goes up 3000% for mothers between their 20's and 40's. Materially, middle-aged people with no kids are possibly financially better off.
But the laws of time and motion are against this argument. Between 16 and middle age, some parents have > 10 children. If you are saying that your one or possibly two children later on will "prevail" against this onslaught, you must be hoping that the 10 never learn to exercise joint democratic power.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
