Xbox cloud region lock

Well no

As Romania isn't a Xbox live region you'd have to wait till Xbox live comes to your region even before gamepass or xgu or even cloud services are even considered

And cloud Services are region locked

No as it's region locked and switching regions would break the cloud

They won't you don't understand how it works

Xbox 360 content is Region locked

She has to be in the region with the same language

Changing your region of the website won't affect your account region

You won't be able to use cloud gaming if you tried as cloud gaming is region based it will make so you aren't in a supported region since you are trying to bypass the region locks

Because she is playing via cloud not by console

She is limited By her region

Consoles.settings have nothing to do with cloud gaming

The language of a 360 games are set by the region of HER account since she is playing via cloud not your console setting

Language independence is a xbox one feature NOT bc feature

Not to.mention latency issues.

Cloud requires a lot of bandwidth

You are better off playing locally.

Then cloud out of region

Bypassing region locks is a violation of TOS and can lead to account and hardware bans.
