When's the right time for client-side caching versus server-side caching?

Hey everyone. I've been thinking about caching strategies a lot lately, and it feels like there's always a discussion about where to put the cache. I'm really curious to hear your thoughts on when client-side caching, like browser or PWA caches, completely beats server-side caching, thinking Redis, Memcached, or CDN edge caches. And of course, the other way around too. Are there certain situations or kinds of data where one just works better, or makes your life easier? Static stuff is a no-brainer for the client, but what about dynamic content that doesnt change often? What's your approach for figuring this out?
