New to LoL & Want to Learn Top Lane

I’m completely new to League of Legends and I’ve decided that I really want to main the top lane. I like the idea of playing a strong frontline bruiser who can hold their own in lane, but I’m pretty lost on where to start. I initially picked up Darius because everyone says he’s a straightforward champion with a simple kit, but honestly… I’m playing him really badly. I keep messing up trades, missing CS, and I don’t really know when I’m supposed to go in or back off.

Could you guys suggest one champion that’s great for a beginner learning top lane? I don’t mind if the champ is simple or slightly more advanced — I just want someone who can help me understand the fundamentals without punishing every tiny mistake.

Also, if you have any general tips for playing top lane, please share them.
