beginner needs Help with software choice

Hello everyone.
Can someone give me some advice please. I am in the process of
setting up a mill and will be using flashcut to run it. I am unsure
regarding which cam software to use to give me the best results. I
want to be able to engrave, and carve wood, cut parts for small
furniture and also ( hopefully, if I can get my head around it )use
the machine with a fourth rotary axis to make carved and turned legs
etc. I have no experience of the different packages so any help and
advice you can give me will be greatly appreciated.
Thank you in advance.
Graham.
