Good prepared spells for a spontaneous caster

[Pronate11]

I am preparing a bard for a stolen fates campaign, as so I am starting at level 11. While I have everything else sorted out, I took Esoteric polymath, and so get a spell book and can prepare one spell each day from it. I have a good chunk of gp left, so I probably have 200-300 gp worth of scrolls to use. Theres a lot a guides on what scrolls to buy, but what spells work well with this limited amount of prepared casting? Comprehend languages and the remove X spells seems like a good start, but what else on the occult list would you recommend?

Mostly these two

Spells that let you act on info you gained previously: Object Reading, Dispel Magic, Resist Energy, Dimensional Anchor, Scrying-like spells...

Spells that belong to a stacked spell rank: rank 3 spells have Slow, Roaring Applause, lvl 3 fear and Time jump. You might want all four of them.

Edit: Don't forget you can also use the feat for double signature spells. Quite useful for Magic Missile and Soothe.
