i used to use [0]s3ql on-top of "slow" fuse storage. it comes with its own caching layer and some strategies around handling larger blobs of data efficiently even at high latency with ease but its a non shared filesystem. you mount/lock it only once at a time. otherwise this was a perfect solution to me at the time.

there is also [1]rclone with its own caching layer and own support for various backends directly. I don't remember anymore why i did prefer s3ql though, but i usually have some reasoning with things like this..
