Very good summary of the current state of thinking. I think current best practice is a combination of the strategies.

I would add a seventh: equity glide path investing. The logic used in target-date funds to counter sequence-of-return risk should be considered for taxable assets as well.

Also, few retirees consider full annuitization. One solution is longevity annuities, which aim take longevity risk off the table with just a portion of one's assets.
