You could look at other products too.

Gitea has been very close to core Github Features IMO and Gogs (the original fork) has some neat other features separate from Github.

There is also Bitbucket which does integrate neatly into JIRA in my experience.

There is a lot of choice, Gitlab is great if you need a "everything in one box" solution for every problem or demand you might encounter during development.

Other Git-Webapps solve other problems or problem spaces.

At GitLab we invested a lot of time on our JIRA integration and we released support for GitLab subgroups in JIRA Development panel yesterday.
