That actually sounds like dirty power. In my office I have
two UPS units, most of the computers run off these.
They clean the power as well as ofc supply power
in an outage. The pi3 running here (also a binary install,
on 14.5-p2 I think) also a dns server (unbound in ports)
is on one of the UPSes and it chugs along just fine
with the three outages we had in the storms last week.
It also has high uptimes, additionally /var/log gets 
mounted tmpfs to further preserve the microsd.

A rpi4 in another room, not on any UPS, running linux, 
lost its filesystem to the extent it wouldn't boot.
Probably when the power went off on off on off on rapidly 
before full power loss, and also the surge when it came back.

for hd health, I find dd works best.
Back up that you need from the disk then something like
' dd if=/dev/your_device_number of=/dev/your_device_number bs=4096 \
conv=sync,noerror status=progress'

run it in a tmux session
