There is no guarantee with this query to get a path, but instead all
ancestor classes for the given class. In your example it might have been
worked, but this is more by chance.

Well the query does what it needs to do, for a given concept find the path to a
root, for example:
query:
SELECT DISTINCT ?parent
WHERE {
GRAPH ?g {
<http://purl.bioontology.org/ontology/ICD10CM/J86.0
<http://purl.bioontology.org/ontology/ICD10CM/J86.0>> rdfs:subClassOf+ ?parent .

output:

It’s just that it’s really slow, so I was wondering if there was a way of
optimising this (either by some hints, or using reasoners that understand
transitivity)

I don't know that you can get such results from sparql directly. I would get
flat list of subclass relations in xml (.srx) or Json and then process with
xslt or JavaScript to write out class hierarchy.
