Forged in the dark are games that use blades in the dark which is a powered by the apocalypse game, so you'll pick them up quickly. Blades is an amazing game so I'd absolutely recommend this.
OSR games are definitely for a specific taste, they try to capture the early TTRPG era dungeon crawl tone over the very narrative forward modern TTRPG, which personally is the opposite direction from where my tastes have trended from 5e.
