I use poweoff generally. On my laptop, the cellular card prevents sleep, and my desktop often refuses to wake from sleep.
Honestly not much fussed about it as both systems boot so quickly that it's not much of an issue.
As for SSD longevity, again not much fussed about it. In the last 20 years I've only had 1 SSD fail so far. A 40GB drive that bought in 2007ish finally failed last year.
