I'll add a "me too" - soft power off rules.  Look into a pi-juice Hat or
similar - it has a battery and can turn off properly either at low
battery, or when power is removed.  Alternatively, a pi is very low
power anyway ... why not just leave it on in a featureless "black box"
with no lights showing and program the remote to to do a fake
"standbay/off" that triggers a script to blank the video and or reset
the screen to the entry menu? (if you are like me, playing with the gear
is way more fun than using it as a media box! :)

I have a few different pi's and similar Odroid arm systems running
Gentoo on sdcards - the failure rate is a real and constant problem (and
seems worse on pi's no matter what brand/type of sdcard so keep an up to
date spare+backups) and I am thinking of doing a disk-less NFS using the
a minimal sdcard image. Has advantages in centralised management and
using small cheap sdcards with possibly better performance.
