I'm reluctant to have any wireless devices with visibility into my home LAN systems (PCs / home servers). So I was thinking of having all wireless devices use the guest SSID. Is this a bad idea? I don't need wireless devices to communicate with other systems on the LAN. They just need internet access.

That all depends on your Router Or AP hardware.
For example if it was possible to setup your ACCESS POINT on a different subnet. Example: 192.168.2.1 and your network is at 192.168.1.x. Then you'd be golden and you could setup all of your wireless clients on guest or 2G/5G.
If you setup your guest in a way, where they don't have many restrictions (for example bandwidth restrictions). Then I don't see why that would be a problem.
You have to remember, not all Routers and/or access points are the same. They all have different default config values or restrictions for guest wireless networks, IF they have a guest network at all.
Lastly, I know you're asking this due to a high level of paranoia (which is ok). But if nothing on your Hard Line computers/devices are ever sharing anything to the network, I don't see how they could access anything that's on a hard line.
