You should surely be fine for the 130-mile round trip to your children, particularly if you drive sensibly in winter. I did a 120-mile round trip in my SR last month and got back with about 19% of battery. No problem. I believe the X-Power can get fuel economy close to that of a Trophy if it's driven like a normal car without showing off its red-shift capabilities, so 130 miles should be a piece of cake.
The thing about your husband's longer journeys is that whatever you buy you are going to have to stop to charge somewhere. It's only about how often you stop. But I've seen films of that NMC battery charging at 140 Kw on an ultra-rapid charger, and they're installing more and more of these around the country. You don't have to stop for long to get a decent amount of extra range at that sort of charge rate.
In a related point, if for some reason you're getting low on charge on a round trip you thought you could do without charging at all, you won't have to stop for long to add maybe five or ten miles of range if that's what it's going to need to get you home. It's not as if you have to fill the battery. I've got a mental note of the rapid chargers on my regular routes home from various directions, and how far they are from home, so that I can decide to nip in for five minutes if I'm getting twitchy. (But it'll probably never happen.)
Congratulations on deciding to get the car. I have been hideously tempted, but fortunately for the state of my savings the X-Power was only a rumour of future greatness when I bought my car. I'll be watching your progress and trying to resist the temptation to talk about trade-in for an X-Power once we've seen how the first adopters get on with them.
ETA: I don't think these cars are becoming obsolete. The technology is advancing in small-ish increments, and older EVs are still popular as second-hand cars. People who bought Leafs (Leaves?) several years ago didn't stop liking them or finding they did their job just because newer models with new bells and whistles came in. I was in the position of needing a new car like NOW because the insurance decided to write off my 2009 Golf GTi due to bodywork damage (an idiot in a BMW came out of a side street and hit me), and I decided to get the MG4 because it was the obvious pick in April 2023, and not keep hair-shirting and second-guessing the decision. I think you'll enjoy the car.
