When I self-hosted my WordPress sites, I used Redis for both object and page caching. I’ve since switched hosts and no longer leverage Redis.
For posterity, my Redis Page Cache plugin can be found on GitLab at https://git.ethitter.com/wp-plugins/redis-page-cache.
The Redis Object Cache plugin that I once contributed to was abandoned long ago. In its place, I recommend Till Krüss’s plugin: https://wordpress.org/plugins/redis-cache/.
