I finished The Legend of Zelda (1986), what now?

Hey guys, I have just finished the original Zelda game and I found myself unable to decide which game should I play now. I have never played the franchise before (maybe excluding some fan flash game where Link could visit McDonald's in Hyrule, but let's skip that...) and my main goal is to finish Ocarina of Time and Breath of the Wild, but I'd like to explore the franchise more and not skip some hidden gems. On the other hand, nowadays I don't play video games that much, so completing every game would take me probably a few years.

I'm playing on Switch 2 with built-in emulator from Nintendo Online subscription, so games older than Wii/DS are there.

Btw. as someone who enjoyed playing The Binding of Isaac, I was thrilled to see how much this game was inspired by The Legend of Zelda! I mean, it's not just the title and battle system, literally almost every gameplay element of Zelda is present in Isaac.
