Both GS devices are brand new. They work correctly, essentially plug-n-play out of the box. Devices wired to the 108 work fine. The 108 powers the 105 fine. Devices wired to the 105, and WiFi devices on the access points on the 105 work fine.
The IP addresses for both devices are visible in the IQrouter's listing but no hostname is associated.
This does read like both switches DHCP client are working and get an IP config from the DHCP server on the router. A hostname is not "associated" - a DHCP client does not have to provide a hostname with the request, so the hostname can remain empty. Nothing wrong to that point

The 108 can't be pinged, no matter where my Mac is plugged in. "request timeout for icmp_seq" even when plugged directly into it.
The 105 can be pinged.
Potentially something wrong or broken on the 108. I would suggest to reset (restet button) and bring it up with jut a Mac or Windows system connected (without any other connection to the router or other systems). More below.

Neither device will provide an admin page at https://ipaddress.
This switch class/models don't support https - use http on port 80.

I installed the ProSAFE utility in Windows, and it cannot see any switches.
There is a nice Netgear Switch Discovery Tool available for both Windows and macOS - perfectly sufficient for the pure discovery (and much less intrusive than the ProSafe Plus Utility with the network capture driver).

I plugged my Mac directly into the 108, did factory reset, tried static IP on my mac and tried the default .239 address. Cannot ping or https.
If you expect the router fall-back to it's default IP address, you must run it without any connection ie. to the router with the DHCP server. Disconnect all network cables, just keep a link to one computer (Mac or Win does not matter - except of that we would have the ProSafe Plus Utility available on Windows).
Both Windows and macOS systems will auto-configure ZeroConfig addresses on the network interface if there is no DHCP server resp. no fixed network config. Therefore, you need to manually apply a fixed (or alternate) network config into the 192.168.0.0/24 255.255.255.0 network - just use unique addresses (not .239).
Now you can try to ping the 192.168.0.239, discover it, or use a Web browser and call http://192.168.0.239/.

This would allow to connect a Windows or macOS network interface without having to temporarily reconfigure the interface to the 192.168.0.0/24 network - but then some additional discovery method would be required to find the "right" address. More and more device firmware is coming with UPnP and Bonjour device announcement - in some years we might see a change in tis direction.
There's already a discovery protocol that could be used: LLDP (Link Layer Discovery Protocol). It can advertise, among other things, the device's IP address. The IP address itself does not need to be link-local. Many, but not all, of Netgear's managed switches support LLDP, so one option is for Netgear to make it available on all of their managed switches, like the GS108PE and GS105PE.

UPnP (in Windows) resp. Bonjour (macOS Safari) are readily available - to my knowledge there is no LLDP "client" or "tool" by default, so its not a choice.

Open source LLDP implementations are readily available for Windows and macOS. SSDP, the discovery protocol for UPnP, has a security issue: it can be used to launch DoS attacks.

Tools and utilities are not user friendly if standards are readily available. I was talking of the default standard OS. Otherwise we're back on the NSDP level and the ProSafe Utility level again ... at least without having a packet capturing and injecting driver on the network stack.

Mostly academic. For networks having UDP port 1900 open to the wild Internet, or having malware and/or bots in what should be a trusted private network environment - then I agree.
This does bring me to the point that most older and current NTGR Smart Managed switches don't have a control to limit NSDP, UPnP SSDP, and Bonjour, and the Web UI to a defined VLAN.

But you haven't given a user friendly solution. UPnP and Bonjour are protocols, not user friendly applications. How did you envision they be used?
