Get an SD card specifically labeled "high endurance." They're a tad bit more expensive, but do work.

Corruption has always been an issue with using standard SD cards as a boot system. It's just something these cards were never meant to do. I run multiple Pis at home, one of them as a scraper/site hosting/MariaDB/Wireguard. Power outages would almost always corrupt the file system, and a few times, damage the SD card. Once I switched to high endurance cards, I haven't had a problem.

I have a datalogger based on RaPi running since around 2 years. It writes every 5 minutes more or less 25 bytes to a file on a standard SD card. I have frequent black outs (and maybe brown outs, too, but never investigated this), and I never had problems with FS corruption.
