Unity Animation Rigging or Final IK or BOTH ???

I'm designing a game that requires rigs to be manipulated programmatically in real time but I also would like some easy parameters type settings that you would get in the Inspector to manipulated the rig also (maybe putting constraints etc etc).

I'm only just skimmed over the two main tools that I believe that are suited for this i.e. Final IK and Unity's own Animation Rigging package introduced in late 2019. Now I know that Unitys' Animation Rigging is still not in a 'production state' as of Summer 2020 but could anyone highlight the pros and cons of using each one and tell me if they can somehow be used 'together' for say the same rig to leverage the benefits of both tools (or would this not be feasible ?).

Thanks in advance.
