I quite like Tailscale SSH for this, but I don't have as many machines, so not sure how it will scale. You can definitely assign roles here to allow/deny SSH between hosts in your fleet though.

I keep hearing this about Arch: could you educate a noob on what kinds of things I'd be dealing with? I'm comfortable with Linux in general but somewhat apprehensive with what I hear about Arch

Ivory for Mastodon also has it, and I'm assuming it came from their Twitter client (never used it myself though)

Did you try manually setting the TDP? In Civ VI I set it to 7W (default graphics) and it has helped quite a bit.

I mean, this is Google we're talking about...
