The /r/LearnJapanese subreddit wiki is still the best place to find this kind of information, unfortunately. Maybe we start to populate our own to rely less on Reddit, but for now, I would start there (main wiki page), with a specific answer to your question being on the resources page.

For a personal answer, I've relied heavily on Anki (flashcard software) with a Core 2000 deck (e.g. https://ankiweb.net/shared/info/2141233552). There are lots of variants of the deck if you search for anki core 2000 deck, but they're all vocabulary lists sorted by how common they are in everyday language. Super useful.

Anki with a Core deck (I use Core 6k) or Torii SRS are pretty solid free ways to learn vocabulary.
