Instead of an error-prone SD card, use an SSD (internal, external doesn't matter).

OR create frequent backups that are pushed to a better medium.

Or just get a mini PC. I have an Intel N100 based one that wasn't much more expensive than a higher-end Pi, housing, wallwart, SSD and adapter, is substantially more powerful, energy consumption is pretty close, and it's potentially more useful if it needs to be repurposed later.

And then set up backups.
