client-side vs server-side caching, which is better

hey everyone, ive been thinking about caching lately and wanted to get the community's take. Were building out a new feature that involves frequently accessed, relatively static data. My initial thought is to implement client-side caching using something like ETags or Cache-Control headers. But, Im also considering server-side caching with Redis or Memcached for faster responses and reduced load on the database. What are your go-to strategies for caching this type of data? Are there specific scenarios where one approach clearly shines over the other? Curious about your experiences and any pitfalls to watch out for.
