Just planning to run on a raspi using raspiblitz. It looks like they have a tor option, so that's cool. Though looking at the Clark moody dashboard they make a distinction between "reachable" and "tor" nodes. Does "reachable" only apply to clear net nodes?

No worries with ISP limits.

For now, I have no intent to use the node for transacting, but rather just validating transactions and generally getting more familiar with the workings of Bitcoin. So perhaps I'm being overly cautious?
