Whose calligraphy is practical and beautiful?

Practical and beautiful: Zhao Mengfu in regular script is recommended (if the social status is high, Yan Zhenqing is recommended).

Running script suggests that you choose either Wang Xizhi or Zhao Mengfu.

These are all soft pens. Of course, if you choose to practice hard pen, I suggest you study the copybook with a pen. The effect is still ok.

Because the artistic appreciation value of Dong Qichang font is greater than the daily practical value, I suggest that you can learn from it if you don't plan to engage in calligraphy for a long time.
