I have not found this to be true.
I think you could get an answer to all of those questions above by downloading the PDF and just going through each section. For example, it has been a while so forgive me if I do not have this exact by memory, but I think you can use similar functions (setting a cutsom axis and angle as you can in Blender) for move and scale in Maya but for rotate and other tools you have to access those functions (setting the pivot point and angle of rotation and so on) either within the tool or by other means. Just an example. I don’t remember which tools were excluded. But the point is there is not a standard across all of the tools like there is in Blender. On the other hand Blender is extremely limited in its manipulation/transformation tool set compared to other programs.
Maya is extremely well developed and I don’t see how you could get all of the answers without going over the manual. The manual is quite comprehensive I have found. That is my opinion based on giving it a recent read through on some modeling and dynamics. I found it to be very satisfactory in covering the various functions in those sections I read. Take it for what it is worth.
I have also watched a lot of the Maya tutorials and that is good too, but not nearly as in depth as the manual. So I think a healthy combination of both might be something to consider.
