I think most PCs will be able to handle SD H264, but just in case, also download the Win version of VLC (a free media player)and offer that as well.
It will play H264 on a PC.

Is this your main footage or is it to go into an existing SD timeline. Why not edit in HD otherwise and then downconvert the final to SD.
There are lots of good ways to do this and a search of the forum will give you all the options. So rather than convert all footage, just consider converting the final so there aren’t “days of render”.

Most important is to convert the audio as well from aac to PCM at 48Khz sample rate. This can be done in compressor at the same time as transcoding to ProRes.ProRes HQ is not necessary.
To answer your other question – no you can’t uprez it back to the original quality if you make it DV codec, but you can make your ProRes file in an HD spec and just edit in HD. This is easy to do in FCP with ProRes providing your drives are fast enough. The pixel size you have been given is strange. Make it 1920 x 1080 which is a proper HD size.

I am not sure why it is necessary to have VU meters. They were designed to measure analog tape saturation and although many people use them to get an idea of loudness, there are better ways to meter that.
I run sound post production as well as onlining with FCP and I haven’t used VU meters for over 20 years. Broadcast legal can only be judged on a peak meter. I would recommend an external meter that gives you the ability to view a variety of metering options including phase, phons, peak and average. This should connect to the AES outputs of your I/O card. I would also recommend an external peak limiter if you are feeding straight into master control.
A plugin is not useful as plugins are clip based in FCP. You do no have the ability to drop on onto a track or master output. Also those sort of plugins have display latency which is useless in critical metering.
These brands are well recognised. Expensive, but accurate & reliable like any good quality external. They also have specific loudness metering options.

Can the transcribers play quicktime files? You can export the audio in a quicktime wrapper as later versions of quicktime player can read the embedded timecode. You could also provide a burn in on the video track or do they need to extract the timecode info automatically from the file? Most transcription services that I use take quicktime files.
Otherwise can they read broadcast wav and its embedded timecode?

If you export an OMF it has the info on where the files sit in a sequence timeline so an OMF will import into an audio system with the file correctly synced to the sequence timecode on the correct track.
Or do you mean a file like broadcast wav with embedded timecode metadata? More info on what you are trying to do will help.

I got a reject so I never trust the broadcast safe or RGB limiter. There were overshoots on edges on a shot sharpened with the Lyric unsharp plugin. Broadcast safe looked good before render and not after. The shot was picked up for peak white spikes over 100 by a broadcast QC.
Since moving to Color, I haven’t had any issues as it does a proper broadcast legal.

In practical terms, the smallest unit in video is the frame. In audio it is the sample. There are approximately 2000 samples per frame of video (@ 25 fps) so many systems allow audio to be moved in sub frames compared to picture which can only really be moved in whole frames.

I got sick and tired of the broadcast safe not being safe after render. I know Walters trick of adding levels may solve this but there is a free luma & chroma safe filter (Video Legaliser) available from https://www.thegradingsweet.com/w2/. Go to the online store and download the demo which includes the Legaliser which is free.
It works before and after render

Before going to Compressor though, you will want to put the letterbox on just to see if you need to adjust framing.
Somewhere there must be a plugin that creates an accurate 2:35 letterbox
