Thanks for sharing these many videos showing how to model in FreeCAD. These are especially valuable if you are making a transition from SolidWorks. They are good examples for training and maintaining one's skills in PartDesign.
I did not review all the videos, but several. I note that in most, if not all, you are attaching sketches to model features (e.g. faces).
This is currently not recommended unless you never expect to make and correct an error or if you do not want a robust parametric model. Any changes to the model features will likely break the model due to the topological naming problem in FreeCAD. Sketches and datum should only be attached to origin planes and positioned as required with the attachment offset property. Neither should any of the features (e.g. edges) be referenced in sketches.
A sound parametric model is only as good as its ability to withstand design changes.
