You’re over complicating things
if you don’t know their use case or the hardware they use
Most hardware will work ootb, most use cases is opening the browser. But i do agree a blank “use Linux” is a bit too broad. Something like “Use Mint” or “Use Fedora” is better.
wine doesn’t emulate, it translates api calls.
Installing dotnet shouldn’t be necessary afaik and might bork the protonprefix further.
