s-maxageshould do the job, though it'd probably be up to the instance operator to decide on a sane value for that, as it will always be a tradeoff.ideally, lemmy would have a mechanism for cache purging, but i suspect that this might be something that people will have to implement themselves using the 1.0 plugin system at some point, as it's probably not going to become core functionality to support e.g. cloudflare cache purging.
Probably both this and cloudflare caching. Looks like I set CF to cache for 1 year at some point, I can lower it... but that won't "fix" this, only limit the time its an issue for.
