Validator Node to best empower the network?

When running a validator node, there are a few major decisions to make: cloud based or hardware, client type, location etc...

I am curious to hear from the community: if you were going to launch a node with not much worry about difficulty and so on, and you specifically just wanted it to empower the network as much as possible; what would you choose for this and why?

You can start with what I listed above, but include any aspects I missed.

For example, I assume diversifying the current client distribution would be one aspect that would be important.

The current state of validator node distribution should be taken into account with regard to all the aspects, too (this is not meant to be a theoretical experiment based on a fixed number of nodes, but rather if you were adding some substantial amount to what currently exists today).
