It seems to me that what the OP is looking for is meatgrinder dungeons full of tricks, traps and monsters. As it happens, aside from a few classic examples (mostly written for tournaments) most old school adventures weren't that, either. 1st and 2nd edition stuff is easy to convert to 5e, but actually isn't what it looked like through rose-tinted nostalgia goggles. For example, Pharoh stands up quite well, but Ghost Tower of Inverness doesn't.
I definitely wouldn't recommend Radiant Citadel. That is full of story driven adventures, not dungeon crawls. However, Bazzoxan (Chapter 3 of CR: Call of the Netherdeap). feels like an old school meatgrinder dungeon. It's a bit short to justify the cost of the rest of the book, although it written in such a way that you could drop in extra levels, or even use the DMG random dungeon generator.
