Which variables should be adjusted when training time is a limiting factor?

I workout first thing in the morning because life.

currently running the bridge. On the mid/high stress weeks, time starts becoming a factor because of the increased volume and my rest periods tend to be a little longer. Which of these variables and in what priority would you adjust to optimize training results?

1: less sleep. I currently about 6-7, going to bed earlier not really an option, but I could get up earlier
2: shorter rest periods I would imagine I would decrease the weight slightly to keep the same RPE. I usually use about 4-5 min of rest on the more intense sets
3: training day frequency increase from 4 to 5 days, is this advised? advice on how to re-structure the workouts if this were the case.
4: decrease volume
5: something else

other things to consider. My warm up is a barbell complex of deadlift/press/squat takes about 90 seconds, and then a warm up of that exercise starting with the empty barbell leading up to my working weight usually about 3-4 sets. for example working up to squat 5@6 it would go Barbell/135/225/285/working weight, 2-5 reps. 0-3 min rest, most of the rest being on the last set. should this change?

Thanks!

What programming are you doing and what are your work sets?

how do you run the bridge on a 4-day split?
