I would think that using your own or using dried fruit without preservatives would give you the best flavor. But I don't know of any reason why using that which has preservatives added would cause any safety issues.

It would just be a personal preference issue. Most who spend the time and effort to make homemade jams do it to avoid all those additives and preservatives that are found in commercial jams. But if they are of no concern then there is no reason why you can't use them.

I use purchased, dried apricots in my Habanero Gold jelly with no adverse effects.

I agree with Dave that for many of us the purpose of preserving is to control contents in addition to being able to use summer's bounty all winter. However, there are some things I just won't do.
I'm not going to buy apricots, dry them, then rehydrate them for a few jars of jelly. :-)
If I had an apricot tree, it would be different!

I wouldn't worry about the preservatives unless it is going to be served to someone with sensitivities to them.
