I found Instant meshes via others who leave snippets of info in their model description (tests by @nebulousflynn, @ivlpaleontology) Wonderfully useful even on my aging PC at home, and command line as well. Might explore ra drag and drop batch file for standard conversions.
I think a tutorial on this would be invaluable. I've been stuck at the data production side of the workflow for a couple of years because I needed to understand that better before moving on to the end and working backwards which is what I normally do. There's a lot of talk about object based learning where I am but the current skill sets sit at either end of this part of the process... Production and presentation. May well be the same in other academic institutions trying to do a lot with a little.
I have a basic workflow now but I don't have enough knowledge to know whether the small glitches are an unavoidable part of the process based on the geometry of the model or something that could be fixed by changing some settings.
I'm also a bit old school... Just because the bandwidth can cope with the data doesn't mean we shouldn't optimise what we deliver to make the most of what we've got. That, and having models crash the browser on a mobile device is not much fun. High res is great if you're providing the data for download for research/re-use but other than that, if you can make it smaller while looking just as good (if not better) for a reasonable effort then why not.
