Most 5W30 oils in North America are API SN and ILSAC GF-5, typical values would be roughly KV100 = ~10.5 cSt and HTHS = ~ 3.0 cP. Thin end of the 30 grade.
Many European grade oils are ACEA A3/B4, typical values are roughly KV100= ~ 12 cSt and HTHS = ~ 3.5 cP. Thick end of the thirty grade.
To be honest, most Ford oil specs seem to be based on the "energy conserving" Euro ACEA A5/B5 spec, which is similar to the ILSAC stuff, but with more rigorous testing.
So I would go a full synthetic 5W30 that was rated A5. Pennzoil Platinum is a good example.
Also at the thin end, another good standard to look for is ACEA A1/B1 oil (almost as good as A5). Plus Dexos1 is another good standard at the thin end. A lot of ILSAC full synthetic oils in North America, such as M1 5W30 and Edge 5W30 are both Dexos1 and A1/B1.
Having said all that, nothing wrong with a A3/B4 oil, I'm using one myself right now. They just sound a little harder to find in North America, plus you said " just normal driving to work everyday", so I'm sure you will be fine with either A3 (thicker) or A5 (thinner).
Just make sure the owners manual doesn't require s special spec like Ford WSS-something. If you need a Ford spec, then better get it. Most good oils carry a multitude of specs.
Ford specification WSS-M2C946-A
There's a bunch of oils that meet Ford's spec, too. Everything from conventional oil - Pennzoil at one point - to M1 synthetic.
