Anything on this list will be fine; all meet Ford's current spec. You can use a syn, but it's not going to give you any more protection in terms of wear control on cleanliness; if it makes you feel better, then by gosh go for it. Same goes for the vis; use what you want off this list; they are all approved. What Ford "recommends" and what is "required" for warranty are two separate things. They may "recommend" a 5w-40 syn, but the only "requirement" to satisfy the warranty is a lube that meets the spec; as shown above in that LONG list. If Ford had separate specs for conventionals and syns, or different viscosities, then used those specs separately for extreme duty service, they could deny warranty based on certain lube choices. But ... they don't do that. ALL THOSE LISTED LUBES ARE APPROVED FOR ALL USES. Don't worry about what your buddy thinks. Read the manual and read the Magnuson/Moss warranty act. As long as the lube meets Ford's spec and is approved, they cannot deny warranty claims based on supposition should a lube be the core of a failure. Ford had ONE SPEC for all diesel grades and base stocks; hence any lube licensed to that spec is approved for warranty.

If you use ck oil make sure it's on the list dnewton linked to. If it's cj rated you can use any manufacturer. Most hdeo are ck now so be aware when you buy.

Motor oil in 2018 is not the same as motor oil in 1988.
There is an interesting statement in "National Oil & Gas News", an industrial newsletter, about the new gas motor SN+ certification:
Preliminary data shows that additives affect oil performance much more than base stock selection or other factors. This should allow for generous base oil interchange and the deployment of the new category in the base stocks that oil marketers need covered. As of press time, the best estimates for first licensing date of SN+ are May 1, 2018. At that time, you can expect to see announcements from all major oil marketers about SN+.
So the argument of paying more for syn over dino just got weaker.
But as others (including myself) have said, if buying the most expensive oil on the shelf lets you sleep better at night, then that is what you should buy.

And in the 1930s everyone thought that drinking whiskey and smoking cigarettes were good for their health.

Sortof. I get what you’re saying but additives in your common dino oil are not the same as additives in the better synthetics. Plus, some synthetics require little to no VI improvers, while dino base stocks still rely on those to meet the multi grade viscosity.
