well you could for example

select="if($a instance of document-node()) then $a/node() else $a"/>

possibly fixes some cases but of course if the select attribute on
xsl:variable returned a document node this would descend into it perhaps

Just not using the xsl:variable with content form is the simplest.

There's no reason to write
<xsl:variable name="v1"><xsl:sequence select="a"/></xsl:variable>
since it's so much longer (and costly) than
<xsl:variable name="v2" select="a"/>
You could write
<xsl:variable name="v1" as="item()*"><xsl:sequence

which then doesn't construct the implicit document node, but that's even
