Switched from Apple to Windows - Seeking overall help

I was previously on Apple (macOS Sierra 10.12.6) using Davinci Resolve Public Beta 15 (Version 15.0.0B.057). I'm now using a PC (Windows 10 Home Version 1709).
1) I'm trying to calibrate the settings to be as similar as my previous settings on the Apple machine.
In the Project Settings > Capture and Playback, my Codec was Apple ProRes 422 HQ. I'm not sure which variation of the DNxHD codec to use now. DNxHD 1080p 444? DNxHD 1080p 220/185/175 10-bit? I'm not sure which one is most similar to the Apple ProRes 422 HQ. I'm mostly editing and exporting 1080 footage.
2) I backed up the local database on the Apple machine and I restored it on the Windows machine. When I try to open a project, dialogue boxes pop up and say "Davinci Resolve does not have write permissions for the selected cache path" and also for the "capture path." When I go into the Project Settings > Master Settings, what is the default Working Folders directory path that Davinci Resolve should have automatically chosen during installation? Mine currently direct to the "C:/Users/Me/Videos" I feel like I did something wrong because I found Davinci Resolve related folders in two separate locations. For example, I see a "Resolve Projects" folder on my desktop (could this be from the local database that I restored?). I also see a "Davinci Resolve Panels" folder in my "Program Files (x86)" folder. I guess I'd like to know where should my Cache, Capture, and Gallery paths direct to?
