I've lived in 5.5 states, and Utah has a ton going for it but prepared for massive culture shock. It's not necessarily bad, it's just different than anywhere else you've lived (and sometimes it can be really awkward). I'd certainly recommend Utah over so many other places!
Wow, there's so much to write I could ramble on about it for pages.
OK, the good. You've lived in Alaska, so I can frame it that way. Alaska is its own critter in its own rite, but maybe to understand: Utah is like a modern Alaska. There's not much to do in the cities, but if you love the outdoors Utah is the place to be--and you can go on a road trip to another state without trekking across Canada first.
There's also very little crime, people are pleasant and helpful, and it is very much a free state that didn't have the impacts a lot of places did with the COVID nonsense (Utah county).
I came to Utah for work, and have lived in Utah county for a little over 4 years. Utah County is about 97% Mormon, or it was when I moved here. That's not bad, it's just different and I am not kidding you about that culture shock. You'll notice immediately when you leave to visit another state. Instead of writing pages, to sum up: it's as white as the driven snow, most things are closed on Sundays, traffic and zone planning are horrid, there are no bars, liquor stores (state run), or coffee shops, the air pollution is the worst in the country, and families are often with 8+ kids so going to the store is a unique experience. Traffic and traffic jams are bad everywhere, but the drivers here are vigilantes and are out to kill you. Drive-throughs are packed between 3PM and 9PM (the Little Caesar's in town often has 20 cars in line... I'm not kidding).
