Default irf510/9510 or irf530/9530

I want an amplifier, and now candidates are irf510/9510, irf530/9530, one is the capacitor current is also small, but small, one large capacitor current is also large, with tl072q driver, who can give me advice?

You are lacking many basic concepts, So Sad, that you haven't done your home work yet and came around asking improper questions.

Do you need it with large capacitor and small capacitor, the small capacitor will be around the driver.

this might be for a headphone amplifier, or possibly for a line driver.

To my mind a common big issue for using mosfets in linear amplifiers is heat conduction, and large-die parts have lower thermal resistance to the heat sink. That would speak for the '530 rather '510 parts. Compare the capacitance, Ciss = 180 or 670pF, that's proportional to area and hence heat conduction. Yep, we see 3.5 vs 1.7 deg-C/watt junction-to-case thermal resistance for the original IR510 vs IR530.

Well, in addition to heat another issue is transconductance. 2 Semens is not much for an output device unless they employ higher voltage so as many can be paralelled. A look at the SOA graphs shows you Rds becomes an issue Vds<5V. I supose the 510s could be used for a power amp, but so could a thousand TO-92 J-fets. Without knowing the indended goals of the circuit we are all just generalizing and guessing.
