Sorry to give you a fifth option but I think it is the best
of those you listed. I often do this graft on tress that are bigger than
the scions but too small to cleft or bark graft. Its a modification of
the whip and tongue, very simple and leaves a good strong union, stronger
than a bark graft. I don't know what you call it and I have not seen any
pictures of it.
Cut the field stock off clean at the height you want the graft. Then cut
the scion as for a whip and tongue graft. On the stub on the field stock
make a cut that matches the scionwood but that, hmm, how do I explain
this, that is a little bit more than half the length of the whip cut you
made on the scion. Notch it with a tongue and then join the two together,
wrap it with rubber strips. 
I have done dozens of these grafts alongside cleft grafts, one-sided whip
and tongue grafts, and bark grafts and these give more takes and more
strength. I don't know if I've explained it very well but does anyone
know what this graft is called?
