If the standard material is .044", including the copper, how would I call it
out using the IPC-4101 designation?

Yes, but vendors call it .044", 6 layers of 7628 laminate (what's a
mil between friends, anyway?). This is a nominal number, and typically
includes the copper thickness.
They may want to consider calling out .044" to reduce confusion.
Here's a link for Nan-Ya Plastics Electronic Mat'l Div. as an
example:

Subject: [TN] FR-4 standard thickness
Good day Technet:
Our designers are designing a PWB using IPC 4101/24 (FR406) material
that's
.045" thick. Is this a standard thickness that is readily
available?
