I want to update this thread given that I've burned in probably a score of 
video captions since I originally opened this thread, so I want to help get 
the message out what worked best to do that task with Windows 10 freeware.

Editing the srt file works only up to a point because you have to look at 
the video and edit the file at the same time, where the biggest problem, 
really, is the annoying propensity of Windows to focus on the wrong window.

So you're always switching your mouse focus between your text editor and 
your video player as you navigate the video with MPC-BE or VLC freeware.

It's a bit worse than that with an editor because when you add a caption in 
between two existing captions, you have to renumber all subsequent indices.

Obviously that means you need a freeware subtitle editor, the best almost 
universally being said to be Aegisub, which is functional, but complicated.

The learning curve for Aegisub is so steep that I went back to text editing
until, in frustration, I tried the "second best" solution, which worked!

This second-best freeware subtitle editor is the Subtitle Edit tool.
https://www.videohelp.com/software/Subtitle-Edit

Subtitle Edit is much simpler and easier to make srt's than is Aegisub!

One pitfall though with Subtitle Edit is it doesn't play well with MPC-BE.
Nor did it seem to work well with VLC, even though it's supposed to.
Nor did it work at all when I manually installed mpv which it recommended.

But when I let Subtitle Edit download mpv on its own, it worked fine.

Those are lessons learned I wanted to impart into this thread for you.
Once you have the subtitles, you still need to burn them into the MP4 file.

For that, Paul's suggestion of ffmpeg has been working out fantastically.
Lessons learned on burning in the subtitles are just in the frill options.

Burn subtitles, 30 point font:
ffmpeg -i input.mp4 -vf "subtitles=input.srt:force_style='FontSize=30'" output_with_subtitles.mp4

Burn subtitles, 34 point font:
ffmpeg -i input.mp4 -vf "subtitles=input.srt:force_style='FontSize=34'" output_with_subtitles.mp4

Burn subtitles, 34 point font, color BLACK:
 ffmpeg -i input.mp4 -vf "subtitles=input.srt:force_style='FontSize=34,PrimaryColour=&H000000'" output_with_black_subs.mp4

Burn subtitles, 34 point font, color WHITE:
ffmpeg -i input.mp4 -vf "subtitles=input.srt:force_style='FontSize=34,PrimaryColour=&HFFFFFF'" output_with_white_subs.mp4

Burn subtitles, 34 point font, color RED:
ffmpeg -i input.mp4 -vf "subtitles=input.srt:force_style='FontSize=34,PrimaryColour=&H0000FF'" output_with_red_subs.mp4

Burn subtitles, 34 point font, color GREEN:
ffmpeg -i input.mp4 -vf "subtitles=input.srt:force_style='FontSize=34,PrimaryColour=&H00FF00'" output_with_green_subs.mp4

Burn subtitles, 34 point font, color BLUE:
ffmpeg -i input.mp4 -vf "subtitles=input.srt:force_style='FontSize=34,PrimaryColour=&HFF0000'" output_with_blue_subs.mp4

The only other thing that's often needed is to set the thumbnail.
What you can do is pick an exact frame you want to be that thumbnail.

This will extract a single frame exactly 70 seconds into the video:
ffmpeg -i input.mp4 -ss 00:01:10 -frames:v 1 thumbnail.jpg

If desired, this will extract a thumbnail every five seconds:
ffmpeg -i input.mp4 -vf "fps=1/5" thumb%04d.jpg 

Once you choose the thumbnail, this will embed it into the metadata:
ffmpeg -i input.mp4 -i thumbnail.jpg -map 0 -map 1 -c copy -disposition:v:1 attached_pic output.mp4 

I hope these lessons learned can help someone else, as I very 
much appreciate the help Paul and others provided to me.
