I think you are overthinking this, if you don't mind me saying so.
If you are applying under H&C, usually the only type of visa they would issue is RC-1. And as we've said above, if you get the visa coded RC-1 there is basically no issue. (If it comes back with some other code, then can ask)
That said: there are reasons to believe you might get refused (which would basically mean revocation of PR status), and/or that it might take some time to be processed.
We can't tell you want is best. But at some point, you either renounce or apply for the PRTD.
