I finally tracked down the issue and thought I’d post my findings. The hack option didn’t work. I’ll post the code I used and you can tell me if that’s what you were suggesting I try. So far as I can tell, the breakdown happens on line 643 of class-acf-field-taxonomy.php in the render_field_select function. $this->get_terms doesn’t return any terms on subsites. It looks like i’ll have to pursue creating my own field that modifies the taxonomy field.

function switchBeforeRender( $field ) {

	if ( ! Site::isRoot() ) {
		$currentSite = get_current_blog_id();
		switch_to_blog( Site::getRootBlogId() );
		set_transient( 'switchBeforeRender', $currentSite );
	}

}
add_action( 'acf/render_field/type=select', 'switchBeforeRender', 8, 1 );

function switchAfterRender( $field ) {

	$originatingSite = get_transient( 'switchBeforeRender' );
	$currentSite     = get_current_blog_id();
	if ( $currentSite === 1 && $originatingSite ) {
		delete_transient( 'switchBeforeRender' );
		switch_to_blog( $originatingSite );
	}

}
add_action( 'acf/render_field/type=select', 'switchAfterRender', 15, 1 );
