Yes, it still stands that the balance point should be on top of the centre of lift, which is close to, but a bit in front of, the middle of the wing.
It does not matter if the mast is mounted further forward or rearward relative to the wing, in this respect.
But it changes the behaviour in turns hugely.
The stabilizer moves the balance point slightly forward, but very little impact, hardly noticeable.
You are right, lift will only increase if you move the mast forward.
BUT, if to far aft so you have to push with your rear foot to "keep" it up flying, it will be even more rodeo and difficult, so just a tad behind the balancing point would be the best for learning IMO, and later move it so you balance.
Just note, that you WILL rodeo like a maniac for a long long time when learning, and what seems impossible will click later
