In the "Specifications" section of the owner's manual (page
384 for the Sedan), note the stated spec for an oil change
is 4.4 quarts. But this spec is "excluding the oil remaining
in the engine." It says the total oil capacity is 5.2
quarts. I imagine if one lets the oil drip into the pan for
awhile during the change, one will exceed the 4.4 quart
"spec." Or if you did the oil change with the engine still
kinda hot (which admittedly is pretty much what the manual
specifies), more oil (especially as you suggest with lower
viscosity oil) might come out.
Overfilled is not good for lubrication. IIRC foaming of the
oil occurs when way too much is present, and so lubrication
is not optimal. Indeed, there is a caution in the manual
about how overfilling the engine (above the high mark on the
dipstick) could damage it. I think the oil change section's
mention that the amount for an oil change is 4.4 U.S. quarts
is so one errs on the low side. Indeed, notice the final
step says to check the dipstick and keep adding oil until
[implied] its between the two marks on the dipstick.
I would continue monitoring the oil level for a few more
days. But I suspect you're fine.
Aside: Did you follow the car's "Maintenance Minder"
direction when you decided the car needed an oil change?

I suspect the oil went into the engine. It would have
dropped even if you had not let it sit but instead checked
right after driving.
