Had wheels installed...is the offset going to cause issues?

Let's say the Ford engineers did their homework and optimized the front suspension and wheel system. Then the stock offset would be correct. Any deviation is a deviation from optimal. So you may be 99.5% fine, which is close enough for most. But think about it, what if you had a 10" positive offset, where the wheel interface was way inside of the wheel centerline. Think of a dually wheel reversed. Intuitively, that obviously wouldn't be OK. So where in the spectrum of your aftermarket wheels to a reversed dually is the magic line indicating "not OK"? I dunno...
I'm just saying that if the system is optimized from the factory and you messed with it, your tolerance for the error is up to you. I learned that long ago with generic aftermarket wheels on front wheel drive cars, which are hypersensitive to change. So when I bought a second set of wheels for dedicated snow tires, I found a set of OEM take offs, and never think about the what if's.
FWIW. Peace.

In general, if an aftermarket wheel manufacturer goes wider, they don't want any fitment problems like rubbing on the inside. So instead of splitting the extra width around the specification offset, they often dogpile the whole amount to move the wheel/tire outwards to avoid clearance problems.
My wife says I try to find things to worry about...

No, I am not saying that. Offset is the mounting face distance from the theoretical centerline of the wheel. If the offset is the same on two sets of wheels, regardless of width, they will give the same resultant load on the hub. My summer Platinum 20" wheels and winter Sport(?) 18" wheels are different widths, but their offsets are the same (size specs are cast into the inner spoke surfaces) so the hubs and suspension don't know the difference. I guess the joke would be on me and my assumptions about precision engineering if the offsets were actually different on some specific wheels!

And an interesting thing about engineers when you talk to them about why they did this or that on a specific brand of motor vehicle that will remain nameless....sometimes they answer with " it just worked and passed testing" or "we didn't have the budget or time to do a complete re engineer" or " it seemed like a good idea and it worked out".
It's just a funny anecdote, now to be fair this manufacturer that I talk about is much much smaller than ford, in fact for the year their entire line sells about a third of what f150s get sold.

Nothing is going to break.
Fun Fact: Different factory wheels have different offsets with different sized tires! They don't always end up in the same position. So that theory is shot.
The factory wheel is designed to fit inside the wheel well, because that's what 99% of people want. As well at its usually a law, you cant have a tire outside the truck without mud flaps because it slings rocks and such. And it effects wind resistance. EPA is not happy about your -24 wheels.
