https://www.theodinproject.com/ is a good, free, guided path, but it does focus on Rails.
I've used https://exercism.org/ pretty decent, does lean into the self guided/struggling learning tho (not everyone is into that).
If you want even more, I've been keeping a roadmap of favorite resources since I started learning Ruby two years ago: https://github.com/fpsvogel/learn-ruby
Then Exercism (free) is amazing for practice
