FD or F is fine, I choose FD for option of dual sim they should support same bands.
According to https://www.frequencycheck.com/models/A34rB/samsung-sm-n930fd-galaxy-note-7-duos-td-lte the N930F/FD support my Tbaytel/Rogers and Bell bands at least, which are 1, 2, 4, 5, 7. (most of my area is B4 AWS)
I think 1, 2, 4, 5, 7 should cover all of Canada, and it has all of ATT & T-Mobile's bands covered as well in case we travel to the US.
Don't know why anything would wipe your storage.
I'd be surprised that you couldn't just boot your system to get stock recovery back, as it should generate a fresh stock recovery from your factory boot image.
Otherwise just flash https://idlekernel.com/flash-tools/...30FXXU1BPH6/AP_N930FXXU1BPH6_RECOVERY.tar.md5 on an F/FD model. I don't have Korean firmware.
Flashing original firmware or updated roms.
If you want to update you flash roms or Odin new firmware. You can't update ota.
Consider before flash anything (Knox tripped), all you risk !!!
Stock firmware for full restore:
