Take a look at this thread for some answers on the CNC side.
My general recommendation is Fusion 360 for a powerful and general 3D modeling/CNC software. We have paid Fusion licenses on our community computers in Textiles and on the CNC computer.
However, it would be a pain to use on the lasers. Vector based software is going to be your best bet there. Adobe Illustrator, Inkscape, Corel Draw, etc. I don’t have any strong opinions there since I don’t do much with vectors, but we do have all three installed on our computers.
