Welcome to the forums, I can only make comments as an observer on embroidery machines.
The embroidery machine my friend has can also be used as a sewing machine. Both of her machine are Brothers and the bobbins are very slightly different and that caused a number of problems until she got rid of all bobbins and bought and marked new ones for both machines. I think it was her previous machine that had issues because it wouldn't read modern USB drives, we had to find some low end giveaway types.
The thing I hear most from people who use embroidery machines is make sure the images/artist you want is available on your machine. And then they want as big a hoop space as possible. And then they complain about the amount of interfacing it takes but so it goes!
