Thinking about how modern dungeoneering would be
A lot of the new tech would be camping gear like super light nylon backpacks and lighter gear in general
Some would bring guns and use siege techniques to navigate the corridors while others believe that bullets are too heavy and prefer a more traditional approach. Especially since we can forge much lighter and better quality swords now (mostly).
You would probably have to get a dungeoneering license similar to a hunting license to enter most dungeons. This is both to prove your competent enough to not get yourself killed in a stupid way like using a gas stove underground or something and also to make sure the dungeons ecosystems are allowed to recover appropriately.
Most popular dungeons have been looted of all the good treasure but many people still visit them to hunt. There are still undiscovered dungeons out there though and if you get lucky you just might be able to be the first to explore one.
Some dungeons are so large and dangerous that they are off limits to the public entirely. Instead they are cleared by the government the dungeon exists within the boarders of using specially trained units. Basically swat but for dungeons.
Magic users and medics are of course always important to have in a dungeon.
Recently there has been a lot of public push back on clearing dungeons. Many people are worried about dungeon ecosystems going extinct and needless to say archaeologists are very unhappy about the whole situation.
Food would have to be mostly nutrition bars and the like unless you want to haul an electric stove into a dungeon. Although a some people do try to dungeon meshi it.
Anyway just something fun to think about
