Yay! -ss and -t with a longer audio.txt file list did the trick!
I appreciate your help!
Cheers,
RS.

Yes. The sws flags are used to control the RGB to YUV conversion. In this
case , full range, and 709 for the matrix

You may want to instead try using "-ss 1.5" in front of one
Many thanks Moritz! Very simple once you know!
A necessary tweak for this task is to move the audio 1.5 seconds forward; I
added '-itsoffset 1.5' before the audio input:
ffmpeg -y -f concat -safe 0 -i /usr/ramDisk/video.txt -f concat -safe 0
-itsoffset 1.5 -i /usr/ramDisk/audio.txt -c copy

Thank you. This works.
Somewhat related question. Does sws_flags have any effect when
converting to yuvj444p color space using scale? (since no actual
resizing is needed)

You can use -x265-params to pass x265 settings. In this case to specify
