Do you scan 35mm slides? It turns out a family member needs this service. If you unpause it, my email is in profile.

TBH 35mm slides are the biggest pain in terms of time-vs-return out of any format. It's a painstaking process and I could not justify the $5000+ cost for a dedicated high-speed machine. But if the end output is ~300dpi for TV display, etc I may be able to help with a fast option.
I think this was in reference to your comment that your side gig that provides this service is “kinda on pause though”. :-)
Especially I wonder if you've got advice on picking a useful level of resolution when digitizing slides. I seem to recall that a 35 mm slide contains around 10 megapixel data. If correct, is it at all useful to digitize at a higher resolution for general purpose usage, eg display on a computer or showing slideshows with a digital projector.
Otherwise I'm currently leaning towards digitizing at 4K resolution as a default, given that 4K is 8.2 Mpx.
How does dynamic range come into play? I seem to recall that slide film has a high dynamic range in general.
