[HELP] NTSC SD master, best De-Interlace?

[Miranda]

I have an NTSC ProRes 422HQ SD master file of an early 1980s feature film:

Frame rate mode : Constant
Frame rate          : 29.970 (29970/1000) FPS
Standard             : NTSC
Color space         : YUV
Chroma subsampling : 4:2:2
Scan type  : Interlaced
Scan type, store method : Interleaved fields
Scan order : Bottom Field First

I need to do the best possible de-interlace to 23.976 fps in order to edit sections into a newer master.

Am I right to use TIVTC rather than QTGMC?

Also, it has slight moire patterning in various scenes. Can this also be fixed?

Any suggestions? Thanks in advance.
