What benefits does Data option provide in Nearby Share?

[MOTE14]

I like Nearby Share and use it a lot. I also have an unlimited data plan, so it is OK that files are sent via Data. However, in my experience, the Data option does not improve performance. I think Nearby Share is sometimes slow and it would be good to have an option that increased speed. What does the Data option do? Can I change some settings to allow Nearby Share to divide load more evenly between Wifi and Data?

As I understand the settings
"Data" means cellular data and WiFi/Bluetooth
"WiFi only" means solely WiFi/Bluetooth

1. Exactly what are "small files" in terms of content and size?
2. When is a file sent via data?
3. What is the motivation behind the existence of the option "Data" if it does not increase the performance of Nearby Share?

Looking forward to your feedback

There's a few apps called "Nearby Share" from different devs. Which app are you actually referring to?

Ah, on my Galaxy Note 20 Ultra it's called "Quick Share", although when I tried it, It never found any other devices to share with.
