Yes, other distributed databases like MongoDB, CockroachDB, probably a few others. Or even multi-master DB setups. As with Cassandra, you don't want to use them unless you really need that availability and can suffer the downsides. It seems pretty rare to actually need those availability guarantees, rather than say a robust fast failover setup which might cancel some in flight transactions. It is probably when you start looking at two phase commit that you look for alternatives with better availability stories.
I remember reading about Discord switching from Cassandra to ScyllaDB I think.
