Generally, I treat the final mora of a word as extrametrical (and thus the accent always falls on a vowel), but I don't know what to do about final superheavy syllables. If normal heavy syllables (CVV and CVC) are treated the same as light syllables, then I don't know if superheavy sylllables should also be treated as light (thus counting two moras as extra-metrical) or as normal heavy (only counting one mora as extra metrical).
This is especially complicated due to the the origins of the superheavy syllables, which by all logic and reason should mean the final superheavy syllable can be stressed if it originates from stressed penult fusing with an unstressed ult).
And of course, there is also superheavy syllables in places other than the final syllables, which would also complicate things.
Perhaps I should just consider the final mora of superheavy syllables to be extra-metrical across the board (though I think that is weird given their origins and also since other syllable types would not be so affected)?
What are your thoughts on this? Do you have other ideas/strategies to employ?

Very interesting questions. Maybe we can split up the problem?
Let's look at final superheavy syllables first. If we assume throughout that only the final mora is extrametrical and that stress in on the penultimate non-extrametrical mora, final superheavy syllables would cause stress on the final syllable. This is what Arabic does, so it should be naturalistic in general.
Penultimate superheavy syllables would act the following, IIUC (again under the assumption that only the final mora is extrametrical and that stress is on the penultimate non-extrametrical mora): If the final syllable is light or heavy, they would cause penultimate stress. IINM, the same is true for your heavy syllables, right? So there would be no actual difference in stress for penultimate (or non-final) superheavy syllables compared to heavy syllables.
All of this assumes that stress is computed after superheavy syllables are formed. I think it makes sense to think about timing, as Sangi mentioned.
If the stress and the pitch accent requirements clash for superheavy syllables, you have a conflict that you could resolve. You could have several options: You could move stress exceptionally to accomodate pitch accent. Or you could move pitch accent to accomodate stress. You could shorten superheavy final syllables and reassign stress as if they were heavy in order to accomodate pitch accent. Serbo-Croation might be a good language to look at for the interaction between stress, length, and pitch accent.
Edit: I started writing this reply before reading Sangi's replies (and your replies to the replies), so I might have missed some things.
