Is it possible to configure
We have a multi-site solution, so ideally we'd like to be able to set these on a form by form basis, but be able to configure defaults as Solution Default > Site default > Form specific.
I've already seen that there are code examples for limiting file size, which is something else we'd like to do.
So are any of these directly configurable, or will we need to code them?

Yes you can define path where file will upload in case of file field. Please see attached screenshot.
