OnDemand is available, but I didn't find a way to configure it through the config files

I've already started on updating the README.

You should be generating the same .conf files as on Android, anyway, and then the instructions for everything can be unified and simple, since the flows and screens are all exactly the same.

Is there a way to carry over the "excluded networks" from the Algo setup? AWS has a pretty low transfer limit on the free tier (30GB), so I'd like to exclude traffic from my home and work Wi-Fi. Otherwise, the on-demand settings, including Wi-Fi vs cellular vs both, are set in the WireGuard app.

Sounds like you want the on-demand settings to filter by SSID? Perhaps we'll add that feature to the app settings at some point down the line.

Correct. Algo asks for the excluded networks at the time of deployment and inserts them into the mobileconfig. It'd be nice (at least while we're using both IPsec and Wireguard) if it could also feed those excluded networks to the Wireguard app. In the meantime, being able to at least exclude IP address ranges would work.

The ability to exclude specific SSIDs is now in the Wireguard iOS app as of two days ago. Existing connection settings can be easily updated using the iOS app, but perhaps it’s time to get that into the deploy process. See (#1328 specifically.) Thanks @zx2c4!
