Play the opening brilliantly, outplay opponent in the middlegame = get a slight, but decisive advantage(around +1 point in computer analise), get to the endgame safe, in better position, ready for a win. Suddenly you look at the board and do not know what to do next: Your pieces are on good positions, pawns moves are not needed, king is ok and your opponent is standing not so badly. Then you begin to think: what i am gonna do, there is no forced, active moves. How to go forward? How even find candidate moves then?

Sounds like you are playing without a longterm plan. A bad plan is better than no plan, so figure one out. Attack in the king side, in the queen side, centralise your king. If your pieces are in good positions, there must be a way to take advantage of that.
Imo you overrate your chances/position(vs the polish master?). After move 25. you say: In this position black has an advantage, but I can definitely try my best to drew the game. I think black has a big advantage and itg is just a technical job to win for black. Your assessment is incorrect I think.
The black bishop is a monster and black is about to rush you over with the center pawns and you cannot stop him. The only chance in my (humble) opinion was to generate counter play with g6 asap at move 35. g6. The idea is to break through to get counter play at the 7e rank for maybe a perpetual. The move 35. Rh3 is a passive(panic?) move try to stop him, but you need counter play instead as fast a possible, not defence.
In the Dragon game i don't like the idea you exchange your Bishop at Bg7 at move 17. It is such an important piece in that variation you (never) want it to exhcange, it is an atacking and very import defensive piece. If you keep the bischop, you can always defend vs the doubling of rooks idea(including Queen). The standard defends move is to play Re8, the bishop at Bg7 and play Kf8 when the enters h7. Now when the bishop is gone he can just push the paws, open the bord and go all in.
