AVCHD files from Canon HF M50

I know the topic of AVCHD has been discussed in a number of posts, but I have a more specific question concerning the AVCHD files coming from my camera. The camera has three "frame rate" settings - 60i, PF30, PF24. The PF30 and PF24 settings are contained in a 60i stream and FCPX identifies these as interlaced material. I realize that the PF30 setting is technically interlaced since the progressive frames are actually simultaneous interlaced fields, but since most of my material is for web distribution I'd prefer working with progressive material rather than deinterlacing somewhere in my workflow. I know about the fix of changing the field dominance of the clips in the inspector, but when I transcode/optimize the media via FCPX the ProRes files created are interlaced.

I also have Compressor and went through the "trouble" of creating some presets for the different frame rates, but doing so left me with a question. In the encoder specifications, ProRes has a checkbox if the files are interlaced indicating a difference in how interlaced and progressive are encoded (naturally). My original idea was to change the field dominance of the PF30 files to progressive in the clip inspector of Compressor so they are treated as and output as progressive. But the interlaced checkbox and the actions of FCPX has left me wondering what the ideal workflow would be when creating ProRes files for material shot in the PF30 setting. Would it be better to create interlaced ProRes files and then use the field dominance override in FCPX or encode progressive via compressor (seeing as the progressive material is in an interlaced stream)?

The worst part about all this is that when I was testing different workflows, Aperture recognized the different frame rates correctly. I considered the roundabout method of importing with Aperture and using these files in FCPX, but I lose some of the metadata of the files which is a pain.

I apologize for the length and the fact that I'm not so much asking for help as I am asking for a recommendation. Any feedback is appreciated.
