Good Wörishofen (part two)

IN round one at Bad Wörishofen I played a junior rated 1704, scoring what seemed a fairly smooth victory.
But going over the game with my main analysis engines (Stockfish9 and Komodo9), a critical position is revealed in the opening.
Spanton (1901) - Anais Abele (1704), Bad Woerishofen B (U2000)
1.c4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3
The English is an opening that particularly lends itself to symmetrical play, with Black usually getting to choose when to break the symmetry. I say "usually," because a position can arise in which White plays a forcing move that Black cannot safely ape.
5...e6
Indeed, 5...d6 is the most popular move in ChessBase's 2018 Mega database, although the text scores a better percentage and has been the choice of Kasparov and Svidler.
6.e4
This is White's commonest reply, setting up a Botvinnik formation, but the position is open to many interpretations. 6.Nf3 and 6.h4!? are the next most-popular, albeit a long way behind 6.e4.
The main point of the text, I believe, is to prevent Black playing the freeing ...d5. Its drawback is the hole left at d4. White will try to get in the move d4 to eliminate the hole, while Black waits for a suitable moment to land a knight on the key square.
6...d6 7.Nge2 Nge7 8.0-0 0-0 9.a3
You might think White would prefer 9.Be3, and that is the top choice in Mega18. But it is arguably a slight positional mistake, because Black can reply with the perfectly timed 9...Nd4!
The point is that White can only eliminate the knight by giving up his bishop-pair, and he would be giving up his better bishop too.
The main line runs 10.Qd2 (White decides to play around the knight, and instead exchange Black's fianchettoed bishop) 10...Nec6 11.Bh6.
Another try is 10.f4, when White might hope to play Bf2 followed by Nxd4. But Black can easily counter this with ...Nec6, ensuring that the d4 knight will be replaced by its comrade.
9...b6

Can White take advantage of Black's last move?

I played ...
10.Be3
... and AA replied ...
10...Bb7
The game continued with what seems to be a novelty ...
11.d4
... and after ...
11...cxd4 12.Nxd4
... White had a pleasant Maroczy Bind (1-0, 56 moves).
But going back to the position after 10.Be3, I had planned to meet 10...Nd4! with 11.e5 Rb8 12.Nxd4 cxd4 13.Bxd4.
But after 13...dxe5 (13...Nf5 is also good) 14.Be3, Black is at least equal, and has what seems to me to be the easier position to play.
The point is that I still have a hole on d4, my d pawn has become backward on a half-open file and Black has a promising pawn-storm on the kingside. True, White has a queenside pawn-majority, but that is an endgame factor that is unlikely to become relevant for a long time, if at all.
