Well, I think I finally got it working! I actually ended up not using this plugin after all, since it wasn’t overriding the subscription settings in the feed setup. Instead, I made a separate PayPal feed for each of the subscription options in my form, with a PayPal Condition configured for each of them. As long as there are no condition duplicates in any of those feeds, it seems to be working great! I have one-time, monthly, and yearly payments all working from the same form.
