I'm not aware of a way to know in advance.

As you said, ports that use the xcode portgroup probably need Xcode, but other ports' build systes might also build using Xcode project files even though the ports don't use that portgroup. Other ports' build systems might require an SDK, therefore requiring Xcode.

Other ports' build systems may expect /usr/include to exist, and may thus require the CLT. I believe Jeremy's work in master is supposed to make that less likely to occur.
