GFI outlets tripped after power outage
Some brands of GFCI’s trip on power loss. I first found this when putting them in on a bathroom sink outlet that was switched. Every time the light switch was turned off the GFCI tripped when the switch was turned back on. I switched brands and the problem went away. I think this was an early safety that today some new GFCI’s make you press test then reset to energize the GFCI for the first time so I would change brands with one and verify the tripping is no longer happening before replacing them all.
