Admittedly, the recent releases of ios have EAP-TLS as a manual choice, and many of my commercial network friends advocate EAP-TTLS instead as most of their supplicants are people who BYOD and are thus user authenticated against a single huge network. For my instance, I want to stay with machine auth; ...

The certificate scripts distributed with FreeRADIUS have been there (and worked) since 3.0.0 was released.

The content is the same as always. Nothing has been deleted. Maybe the screen caps aren't up to date with Windows 10, but the basic process hasn't changed.
How about giving information about what you tried, and what went wrong? "I tried stuff and it didn't work" isn't helpful.

I do recall a very in depth slide show a bit ago discussing that topic.
Most of that discussion is nonsense. You can do EAP-TTLS with client certificates if necessary. The whole "less secure" thing is because people remember passwords. They don't remember client certs. But it's possible to install the same client cert on multiple machines. Just like it's possible to enter one password on multiple machines.

My deployingradius.com site works. If you have *specific* questions about one step, ask.

Use client certs with TTLS. Many supplicants support it.

Tons of people use EAP-TLS, FreeRADIUS, and Windows 10. It's fine. It works.
