Technically there is no need to ask users to agree to anything. If you
just want to make users aware that it is open source then that's fine

That seems fine. Since we don't need them to read any licenses or
agree to anything then it's good to keep it simple and short. Users
can go find more details if they want.

That would also be perfectly reasonable.

I can't remember what the windows one does, but the linux distro
packages of course do not display any text at install time. They do
all include the license as part of the installed files, and perhaps a
