What's the 'lean' option for building CI/CD with JIRA and Github (inc Github Actions)?

Hi, 'newbie' here.  I'm sure this question may not be just appropriate to this group and may need to be re-posted to other specialized group in the community but here goes...

I've been on and off user of JIRA over my career but I've been given responsibility to be JIRA admin and build the tools that will allow us to be an efficient Agile team.  I've done continuous integration in other company setup before but since I've been away from JIRA for maybe 4-5 years a lot has changed with the tool that I'm not even sure where to start to build our CI/CD pipelines if I'm the one to build it for our team.

First, we're migrating from Azure Dev Ops on-prem server to JIRA cloud.  We think that's a win for us.  Of course we'll have to change our mindset how we do CI/CD with the different style of integration.

Let's say I've got Github Actions workflows available to say run unit tests, make different builds for different environments and even deploy to TestFlight, for sake of discussion for our iOS app.

How do I get as close to the prior experience of Release Pipelines in Azure Dev Ops in JIRA? Any articles available out there as a guide, and add-ons I'd look into?

I see the 'Deployments' and 'Releases' tab for example with sample screenshot of just plain Smart Commits to reflect Github status (but maybe I'm mistaken it's just from Bitbucket Cloud integration?).  What other things do I need to take note of to integrate Github Action tasks to show updates back to JIRA - I'm guessing I need to add steps to reflect status back, again I'm not sure.

I'm not keen on using Bitbucket Cloud as we've invested in Github Actions to simplify our iOS builds especially for hosted runners.  So I hope I can get enough recommendations avoiding it first :)
