I’m setting up DHCP reservations on my home network and came up with a simple schema to identify devices: .100 is for desktops, .200 for mobiles, .010 for my devices, .020 for my wife’s, and so on. Does anyone else use schemas like this? I’ve also got .local DNS names for each device, but having a consistent schema feels nice to be able to quickly identify devices by their IPs.

For work we have standards, ideally we separate VLANs by device type and firewall off their communication, but on a home network, I'd generally group by category. .1-9 network gear like switches and firewalls. .10-19 IOT. .20-29 servers & NAS. So on and so forth.

I see no reason to put iot devices on the same lan as my servers/home network, and I never suggest that to friends.

So separate WiFi name or (or probably router/AP) for separate vlan?

That's what I do. All my IOT stuff that I can't get wired or via Zigbee/Z-Wave goes on a separate VLAN along with my Home Assistant server. I have an mDNS repeater for ease of access to TV stuff via apps (might spin TVs off into its own VLAN, just haven't gotten around to it) but a 1-way firewall rule that only allows the main network to initiate connections. Certain devices which don't need internet at all get static IPs and completely firewalled.
