I’d run through PragProg’s Agile Web with Rails first, and then The Rails 8 Way if you want a reference. Books are good, but jumping into videos from GoRails or Drifting Ruby might help more with real world patterns and problem solving with Rails.

Rails website has its own guide which is very good on its own!

Not sure if this would be helpful, but your question reminded me of this classic: https://poignant.guide

Ruby on Rails tutorial by mhartl et al would be my go to https://www.railstutorial.org/
