If we are trying to emulate 5e as close as possible a delay is not part of DnD 5e.
Jeremy Crawford the lead dev of 5e says this from that asked question:
"There is no Delay/Hold/etc. action in D&D. When it's your turn, you either act or don't act.
If you decide to do nothing, I recommend taking the Dodge action.
If you want to act later in the round, use the Ready action"
Which leads us to the problem that we also dont have a Dodge Action. For any of you that are not familiar with Dodge Action, You dodge until the start of your next turn and all attack incoming to you will be at a disadvantage. Dodge is a major tactic used very often in tabletops for survival and if you really have nothing to do at the moment you do that.
Also to Clarify on the Ready action, you consume your action based on a specific trigger cant be anything ( I cast shocking hands when that specific mob comes within 5 feet ) That is to prevent everyone just passing over and over as its a combat resource.
