I've been looking for some time for a jelly bean MOSFET with these specs:

A big brother to the 2N7000/7002. The IRLML2060 seems to fit the bill
nicely but I'm having trouble finding it here in India. A bit pricey for
a jelly bean part anyway.

AO3400 family are cheap but miss your gate charge spec
 

I have AO3400 & 3401, about US$0.03 from AliExpress before India blocked
the site. But these are 4-5A devices with correspondingly higher Qg and
Ciss.

Did you measure them?  I got one batch that measured 647pF and 0.97
Vt.  Later another one measured Vt = 0.87, C = 413pF.  They had
higher Rdson, so not really AO3400, but were closer to your spec
than real AO3400.  Of course, trouble with AliExpress is that
you do not know what you will get, especially concerning mosfets
(sellers routinly sell much smaller mosfets marked as bigger ones).
