First advice must be to mount FS in read only mode, mount /var in memory and forward al logs to one nide, which may be not RPi but something with proper UPS and nut running. Power loss becomes absolutely bening if your FSes RO or temporary.
It is overkill if you have one RPi but author claims that he uses multiple RPis all around a house.
Also, good idea to have A/B system partitions and upgrade system with full partition rewrite and changing active one. Thus way your system will have one good system partition in any case, even if new version has fatal bugs, and recovery become trivial.
I'm using several small/single board PCs im different roles in such way for 20+ years with great success.
