FFMPEG and AVC-Intra Class 100 1080p 59.94/60p
Use -r 60000/1001, not -r 60:
ffmpeg -i "test.mxf" -y -vcodec libx264 -g 1 -pix_fmt yuv422p10le -r 60 -x264-params avcintra-class=100:interlaced=0 output
As shown in your screenshot Adobe Media Encoder is outputting 60000/1001 (named "59.94" which is a truncated nickname), not 60 fps.
