For CCNA R&S, I used CBT Nuggets, Wendell Odom's book, and Todd Lammle's book. For labs, I had Boson labs thru my school but I think you'd be fine with either some eBay gear or Packet-Tracer labs.
For the new CCNA due in February 2020, there's already course materials out there and available.
CBT Nuggets for me was Jeremy Cioara, who is really engaging! My partner (db admin) would eavesdrop and crack up.
Wendell Odom dives into detail more, but is very dry.
Lammle was a little more surface level, but more engaging.... to me. I've had coworkers tell me he's also dry, but networking is My Thing so I was pretty happy.
Pluralsight also has some older courses that still overlap with the new requirements. If I had to get one online training, I'd get CBT Nuggets.
