I studied oils since before I started driving in high school. What I found was that right out of the can Name Brand oils labeled as 30 wt. were anything from 5 to 35 wt. Pennzoil was right in the middle of the 30 wt. area and I stuck with that oil for years based on my initial testing.
When 5W-30 came out I used that and when the 0W-30 Mobil 1 came out I used that oil. When I discovered that my Ferrari Maranello was delivered with a 30 wt. oil I went to the 0W-20 Mobil 1. I had it in the Expedition as well.
I grew up in NJ and spent a decade in NC while training in Chapel Hill so I have some cooler weather experience but have been in Florida for the last 15 years.
While known for running thin oils I have had most cars for 80 - 100,000 miles or more until recently. I always felt the cars were just then fully broken in - when I let them go. No car burned oil and all oils were changed when I could see the oil on the stick or at 4,000 miles at most. I have never replaced a battery*, starter, alternator or any part of the engine. I think that changing brake fluid every year keeps that area good as new and replacing coolant properly keeps the radiator and water pump as new. I have kept away from all additives. As a biochemist I can tell you mixing things is way too complicated. Any chemist can throw together additives but making them work correctly is nearly impossible.
Changing things often in the “fluid” department keeps it all working and thinner oils decrease under hood temperatures and battery starting load and therefor alternator charging loads, saving wear on these parts. You have to look at the whole picture. Many cannot put it all together.
HTHS is but one number in a thousand. By itself it means nothing in my book. There are many reasons to use the thinnest oils that give you an acceptable UOA. If the wear is OK why go thicker? About every other aspect is improved with the use of the thinnest oils that do the job in wear protection.

Note*: I bought 4 or 5 year batteries and replaced them at 3 or 4 years - before they went. Now I have a tester for batteries and am planning on going for the full warrantied amount or longer. Make sure you put water in the battery every January, even in the “no maintenance” batteries. This is one of the keys to batteries.
My cars are as helicopters. We know how long each part lasts. They should be replaced before they go. I do not have AAA and have never broken down. It is called maintenance. Ask owners of airplanes how often they broke down.
Obviously we here all take care of our cars better than most others. We argue over the smallest things. Think about the other parts of the car though. You will be a better person for it. A car is not just a main bearing.
