Just turned 60,000 miles on my wife's 2017 Hyundai Santa Fe XL w/the 3.3. Oil changed with Valvoline Advanced Synthetic 5w/30 between 5,000 and 7,500 miles.

ZERO issues thus far with the vehicle.

What did Hyundai recommend for your OCI's, and what weight of oil?

5w/30 conventional oil is recommended as is 7,500 mile intervals.
That seems about right for engines using a 5W-30 weighted oil. I'm assuming yours is not turbo?

Seems like small-displacement turbos with DI using thinner grade oils (like mine, 0W-20) are needing to get the oil changed more often. I can see from the comments.

No turbo. Good luck with your Hyundai. We have received good service from ours.

2014 Kia Forte 1.6 T-gdi.

Photo taken with 8000km on the oil

Looks clean.

I have a 2021 Kia K5 with the 1.6 GDI. My manual recommends 0W20 at between 5000 and 8000 km. I use 0W20 or 5W20 in the winter and 5W30 in the summer. Both at 6000 km intervals. I used this same strategy with my 2011 Kia Optima with the dreaded 2.4 GDI and never had a broblem with it. I mostly use Penzoil but will buy whatever is on sale.

Did the use of a higher weight oil impact your gas mileage in any way?

On this note, I've been using Pennzoil Ultra Platinum for the past 10 years without looking at others in my old ST. I haven't been following the tech lately; but I like PUP in that it's a true synthetic (gas-to-liquid). I'm sure it's appropriate for use in the smartstream 1.6T. But are there any others that would be even better?

Nothing is better or worse. Its for you to decide on 'marketing' for whatever spec you want for you HyundaiKia product. There is no best oil.

Weather permitting, I'd go as thick as possible. Maybe consider a 5w30 synthetic and go from there.

The higher GDI PSI will reduce soot buildup. I didn't know that Hyundai stepped up to 350bar already. And, GDI pressure doesn't determine compression ratio.

I would not exceed the recommend oil and filter change interval no matter how fancy the oil marketing is.

Delphi claims that its industry-first 350-bar system reduces the size and number of particulates by up to 70 percent and that its forthcoming 500-bar system betters the former by a further 50 percent.
