@Steven_Kell I’m so glad you asked this question because it was precisely that question which led me to make a 3 hour YouTube workshop for JuliaCon 2021 on Julia REPL Mastery (which Jacob already kindly mentioned).
I think I go over all those things you asked for and more.
I definitely need to find time to chop up all the lil’ nuggets into bite size 30 second videos, but that’s what the new year is for I guess.
