The translation of the world into “single” does not seem sufficient as the word just not means single as virgin or bachelor, but also widow/ widower divorced male or female so perhaps “singled” is the better way of putting it…and then other criteria are also there like pious ones and with will and liking ;)
Not amazingly you would quote other people of course in using of the words “Allah encourages” (perhaps your way of putting blame on others when the TIME comes right;))while Allah Himself right in the very start of the Surrah Noor is telling you that in this Surah Allah SWT is giving orders that are FARTH(hope you know what it means) and are clear cut!!!
A gentle reminder this is the only Surah that starts with this emphasis about ahkamaats/orders in it( not that I ever consider any other by Allah SWT any less valuable)
So there are NO suggestions as you put it and NO ambiguity in these orders and this is true for all orders throughout the Book!!
Before going further tell me are you going to contradict this verse from your religious experts’ suggestions? Cause if you are I have nothing more to say to you neither about your other authorities as Allah has ordered me not to bad mouth other peoples Gods!!
Allah does know the best but only if you knew that!

Allah helps those who help themselves!
thanks
