Legend
I would tend to give short rests to all those situations. The rogue and wizard are trying to figure out the trap and the warlock is sitting around 'doing nothing'. My group tends to agree that party members are acting part of the party and not as loners, so the warlock might be doing something. Small things like making tea or looking around, maybe binding wounds of others or building a fire, things that help the party instead of just taking a nap. I would even go and say that the rogue and wizard get a short rest since they are not doing more than figuring out a puzzle or trap/lock. Part of this time is sitting there thinking which can be spent binding wounds or drinking the tea someone else prepared. It is no more stressful than walking to poke and prod a puzzle or lock.
The situation where everyone is waiting on an ambush might have me ask for a Con check to see if they stay on high alert. I laid on plenty of ambushes and know that not everyone can stay on high alert for longer than a little while, especially if the ranger is going to alert them and give them a bit of time. While you may not light a fire and cook a meal, you do bind wounds and could eat dry rations. Also, how many encounters like the one in LMoP do the PCs walk up to a cave or entrance to a module and the 'guards' get disadvantage to Perception since they are not on high alert. I'm running Forge of Fury and the same thing with the initial encounter with orcs on guard at the main entrance.
