Global Cache & WP-CLI Support

Thanks for the wonderful plugin. It performs wonderfully as per specs. I had two queries:
1. How can I set a global cache TTL? For ex: If I want caching to be done for 60 minutes globally (across the board), how do I specify the same?
2. Is there WP-CLI support to flush cache? I noticed that there is a command in wp-admin called “Clear Object Cache”. Is there a WP-CLI equivalent to it? The reason I ask is due to Transients. There is WP-CLI support to delete transients. It would be really useful if both transients & object cache can be cleared from CLI. That would provide a reliable way to flush the cache + transient in a single go.
