Hi, I can't speak on everything you tried but can help a bit. I have Crossover and to have it open files you must add the extension .fh11 for your FHMX files. That works for me on Mavericks. Crossover has limitations however; you need all your fonts used on the file loaded into it. It also has rendering problems with very complex FreeHand vectors. But that said, I use it for all my touchups, quick editing, creating logos, and infographics.
FYI, I have Snow Leopard/FHMX as a separate boot drive so I will boot to that for projects. I don't have virtualization software added...yet. Maybe one of the members can help you there.
