The closest thing to beautiful football in FM might be using short passing and wide width. You can achieve this with either:
AM/STs in support roles and overlapping/underlapping full-backs and central midfielders in attack roles.
All Players in Support Roles,
Even with these instructions the majority of goals and assists will be with the AMs and STs.
Roam from Position makes the player move toward the ball vertically in the attacking phase, it makes the attackers drop to the midfield(second third) when the ball is in the midfield and makes the midfielders enter the attack(final third) in the ball in attack. It makes the player move forward less(less penetration) and move toward the ball more(more support). In practice, it only works with either a support player with Roam from Position and an attack duty overlapping from behind or an attack duty player with Roam from Position. Again, the attackers(AM/ST) will have the majority of goals and assists.
The fundamental problem is that players have a "glue" in them based on their position that makes them return to their position. Even if you give them attack duty they will eventually return to their position and this also happens to attackers. This naturally limits defenders' and midfielders' contributions to goals and assists compared to attackers.
For example, Luizinho was a Central Defender. I think he scored a goal for Brazil in the 82 World Cup. He would overlap from the central defender position and appear in the box to score goals.
In the old Tactic Creator you were free to customize everything, you could give defenders Very Attacking mentality and attackers Very Defensive mentality but giving full customization of all Player Instructions created problems for the AI and it was replaced by the individual roles that we have today. Hopefully, the next version that is coming will add new roles to the game to allow this type of football.
