Sketchup is a "direct" modeling software, while FreeCAD is a "parametric" or "history based", so most of the things work totally differently. Here is a nice article comparing these different approaches in modeling software: https://www.bluentcad.com/blog/parametric-vs-direct-modeling/
So the biggest problem won't be to find similarly named commands in FreeCAD but to learn about this completely different way to model things.
