I've spent a decent amount of time on the FreeCAD Discord and more than one advanced user on there suggests treating FreeCAD like a rolling release. So I've been using the weekly FlatPack builds and have had a great experience. FreeCAD has been taking some big steps recently and by sticking with 1.0.0 / 1.0.2, you're basically missing out on almost a year's worth of improvements.

And the tutorial by Mango Jelly Solutions on YouTube are fantastic. They are generally very focused on one particular task per video so I think you'd find them really useful.
