I'd been rendering using the NV encoder which results in the progressive checkbox being grayed out, *but checked*
I'd been hoping that the fact that it was checked would mean that the moov atom would be at the start but I just uploaded an hour long 1080p video and YT spent 30 minutes (or so, I wasn't really timing it) processing on the HD version after the upload had finished.
So now I'm not sure if I'm rendering for quality and fast upload/availability on youtube.

That is because it is not progressive download.

 

Progressive Encode ≠ Progressive Download

All streaming video is encoded progressive. That means that it is not interlaced.

Fast Start aka Web Optimized aka Progressive Download acts as an instruction for the decoder, not the encoder.

It is not a requirement, although it should be.

You can change your NVENC video to progressive download with MP4FastStart, ffmpeg, Yamb/MP4Box, or similar.

So now I'm not sure if I'm rendering for quality and fast upload/availability on youtube.

You are doing neither.

YouTube has offered supported format list and recommended upload settings, you can check them before outputting rendered video:

I've been rendering my 30-60 min video with the format MAGIX HEVC/AAC MP4 for youtube upload. However, the audio and video are not matching at the end. I'm new at this! Please help!

Will switching to AVC help??

Is Sony AVC/MVC better?

Thank you very much!
