Giving all Fighters maneuvers is one of the most common Fighter homebrews around. In general you’re right, it does give them far more to do. And is just more fun while also being more powerful. Some of the best homebrew accounts for this.

That said, the issue of maneuvers remains the same. There are some far better than others, and any Battlemaster or now just Fighter will pick the best at the earliest convenience then get less useful ones as they level up. Effectively making higher levels weaker in terms of choice and effectiveness.

I also believe Tasha’s added a Fighting Style that just gives a maneuver or two if you want to look at that.
