Can someone recommend software for a Janome Memory Craft 400e?

I just got a machine and this is my first foray into machine embroidery. I'd like to be able to create, edit, and manipulate images, do wording, and monograms. I've looked at several "review sites" <eyeroll> which are more about their affiliate links than the software itself. I looked at one program that specifies it's for machines with 4"x4" and 5"x7" hoops, neither of which are compatible with my machine. Suggestions please.

Bonus question: are there any after market hoops that fit this machine? I've seen ones for Brother machines, but not Janome.
