Which med is best would be a call best left up to them. They are very much in tune as to what is going on & going around in the aquatics community, any resistances to meds that are common, and what works best in a given situation.
Water changes to maintain water quality are the best thing to do for now, good planning with the spare cycled sponges. Those are cheap easy insurance, I wish more aquarists would catch on to that.
I've healed some pretty torn up angels that ended up being in the wrong place at the wrong time during pairing. Large water changes & a little melafix healed these fish up, some with eye damage. It is worth working with fish that need a little help, I have one large black male that got so torn up a couple of years ago. It took a while, he healed, paired with another black, and the produce spawns continually.
The medicated Jungle food is a good product, I've never used it but heard plenty of good things about it. You might want to try holding a pinch underwater for a minute, let it get waterlogged it may sink.
