void QTreeView::resizeColumnToContents(int column)

It's a slot, so when you add data, call it and it will do it for you ;-)

QTreeView::resizeColumnToContents(int column)

If of interest to anyone in the future, iterating over the columns and applying this is quite trivial:

#!/usr/bin/env python3.13
import \
    builtins, \
    PyQt6.QtWidgets

self.tree_widget = PyQt6.QtWidgets.QTreeWidget()
tree_widget_header_labels: builtins.list = ["Name", "Location"]
self.tree_widget.setHeaderLabels(tree_widget_header_labels)

# Iteration:
for i in builtins.range(builtins.len(tree_widget_header_labels)):
    self.tree_widget.resizeColumnToContents(i)
