I will say that back when Bugzilla was it, JIRA rocked. It was amazing the new power you had and the functionality it provided.

We self-hostd JIRA from 2008ish to 2014ish. (memory is fading on exact dates) By the time we decided to stop using JIRA, we fracking hated JIRA and would never return.

Since then, GitHub Issues, Trello, Clubhouse (neé Shortcut) all provide less friction in day to day use. As an Enterprise, I do believe Shortcut is your best bet.
