> we have somebody who has somehow obtained a "weird" video file
Why are you arriving at the conclusion that this requires complex software, rather than just a simple UI that says "Drop video file here" and "Fix It" below? E.g., instead of your conclusion "stick to your walled-garden-padded-room reality where somebody else gives you a video file that works", another possibility is the simple UI I described? That seemed to me the point of the post.
This is really just my read for why this sort of software isn't more common. Go ahead and make it, and if it ends up being popular I'll look the fool.
I don't think that's true at all. The tool linked here is exactly the kind of utility that does one single task and that people are happy to download. Most people use software to solve a problem, not to play around with it and figure out if they have a use for it.
When we moved to Canada from the UK in 2010 there was no real way to access BBC content in a timely manner. My dad learned how to use a VPN and Handbrake to rip BBC iPlayer content and encode it for use on an Apple TV.
You had to do this if you wanted to access the content. The market did not provide any alternative.
Nowadays BBC have a BritBox subscription service. As someone in this middle space, my dad promptly bought a subscription and probably has never fired up Handbrake since.
That’s not always a possibility. See for example:

Those people didn’t need or want Photoshop or a complicated program with tons of options to convert image formats form anything to anything. Even a simpler app like Preview implies knowing where to look for the conversion part and which format to pick. They could have done instead with a simple window which said “Drop File Here”, and if it’s an HEIC, convert to JPEG. Could even have an option to delete the original, but that’s bout it.
There’s an Alfred workflow which is basically that. It does have some configuration, but the defaults are sensible and doesn’t let you screw up the important part of “detect this format which is causing me trouble and produce a format which will work”
But then you have to remember the names of 200 distinct software that all do this one thing, so you make a meta-software to manage and organize them, and you're back to square one only with more indirection
The solution in such cases can't reasonably be "everybody around the world learns to download one particular tool to fix things". In your example, the two reasonable solutions are either apple figures out how not to send image files to people that they can't understand, or the college board figures out how to convert heic into jpeg themselves. Otherwise, as in that case, most people will simply be left in a lurch.
Google could do this years ago.
It might be a problem that you have to search for the solution to every time you have it, but you'll find the solution quickly because many other people also experience the problem.
