In general for any ES use case you should be running only ES on the ES nodes, and yes, you should use min(31, RAM / 2) as heap size. It’s also worth considering shard counts for indices and disk layout in the ES nodes.
As Nick points out, you’re also going to find it hard to tune ES for large numbers of applications running different indexing, so it’s generally a good idea to build different ES environments for your multiple use cases.
