It looks like a, c and d are the main contestants in other people's replies, while b and e are considered to be too slow. I feel the same, my order of preference being d, c, a, e, b.

But in the current AI era, I would definitely consider f and g as well. Didn't you consider those?
I might play f, and if white responds in a passive way, continue with g.

I didn't.

Move G is met with a top left corner reinforcement. Then Black turns to the bottom again.

@Knotwilg: there is no

In such positions, this late in the opening, I now ask myself, Where would Shusai play?

Before the AI era, I would probably have chosen d, because c invites the jump to g, which looks too good for White. But I don't think that that would have bothered Shusai. So c is now my top choice.

I can't speak for Shusai but the c-g-exchange is exactly my reasoning why I don't want to play c. I consider White's gain as more promising than Black's due to Black's corner aji (maybe c ends up being too close to Black's corner position later on?).

I would have played d in this position. Funnily enough my first choice in the top left would have been where X marks the spot. But my joseki knowledge is pretty non-existent nowadays so I might miss a continuation where White uses the attachment to make the extension a good move (then again it still faces Black's strong position on the right...).

Move G is met with a top left corner reinforcement. Then Black turns to the bottom again.

I would not crosscut. I think that is a bit too much.
I would be thinking of a counter-hane, but the ladders towards F7 are bad for black, so perhaps the attachment at K4 is unreasonable.

If black cannot get more than that, then white is probably happy with those exchanges on the lower side.
So maybe black should hold back a bit and play the shoulder hit at J4 instead of K4 after all.

When black starts with the attachment at D17, white may still revert to the same variation as when black started at E18, but in a different move order
