Honestly, maybe the Dali should let people in, probably safer than most places:
"the museum was designed to withstand 165 mph wind loads from a Category 5, 200-year hurricane and includes 18 inch, cast-in place, reinforced concrete walls and a 12 inch thick roof. Storm doors shield the vault and galleries, which are all located on the third floor, protected against 30 foot hurricane storm surges. All of the glass is one-and-a-half inches thick, insulated and laminated, and was tested to resist the 135 mph winds, driven rain and missile impacts of a Category 3 hurricane."
Outer Wilds is one of my favorite games. If he likes the explorey/other worldly feel of souls games, he might like it, but it certainly doesn't have any combat.
As for fighting, I've recently started replaying Returnal, and I really enjoy that. It's a well known console game, but I think it came out after 2020. It's a roguelike format so slightly different from souls, but I love it.
