Udemy has a few good tutorials, but on Youtube check out Tutemic's code architecture course[0], HeartBeast[1], GDQuest[2], GameFromScratch's Godot tutorial series[3] and CodeWithTom[4].
And of course on the blue website /r/godot and /r/madewithgodot
I'll also add in the Godot recipes by Kids can Code, don't let the name fool you they have great miniature tutorials for implementing all sorts of common things in Godot https://kidscancode.org/godot_recipes/
https://youtu.be/SQ7soQ-N-eQ this is the series I started out with. Would recommend it as an easy intro to 3d. I had tried pygame and pandas3d before but none of them clicked like Godot
It was a very simple process, there were one or two typos I found in the code that an experienced programmer should be able to resolve themselves if they haven't been fixed yet.
I haven't done more yet since but would like to. Unfortunately playing games is too fun.
And of course on the blue website /r/godot and /r/madewithgodot
