Just a thought... but would a person's chance of getting a FP for FOP improve if they didn't have an ADR or other FPs already selected? It seems to me that those times would be blocked.
You can ignore any ADRs. They don't interfere with FPs.
Below is from one of the FP+ Sticky Posts on this board.

Instructions for Checking Availability
You don't have to Cancel when checking availability, rebooking a new park, or when park hopping. Simply follow the instructions below.
From the app:
~ tap the "+"
~ select guests
~ select date and new park
~ continue beyond any warnings
~ you won't lose anything if just checking availability. After checking, back out of the window and your original FP+ remain.
~ when you confirm a FP+ for the new park, that's when any original FP+ are replaced.
Checking Availability for Same Park - Same Day
From the App
~ from a booked FP, choose "Modify”
*(Note: to check availability of a Tier 1 attraction, you must choose an existing Tier 1 to modify.)
~ scroll through selections to see availability
~ original FP remains intact if a new ride is not chosen
* The system does show ride availability for time slots that are blocked by original FP Return Windows.
