When I used to use rpi's I had a series of steps I would take to reduce/eliminate most writes, while not turning the system full read-only. Simple things like disabling all unused services, moving tmp and syslog to a ram disk, stuff like that. Combined with a good quality sd card and power supply, none of my raspberry pi's had an sdcard failure in years. I've since moved on to more properly "embedded" type devices (ESP32 and Pico) but not because of sdcard issues.
