السلام عليكم ورحمة الله وبركاته أحسن الله إليكم Is it recommended for me to marry an Arabic speaking woman in order to better learn Arabic as a student of knowledge? Is this something I should prioritise?

It is a plus not a the main thing. The main thing is piety, religiousity, and manners amongst other things as well like beauty and speaking Arabic etc.
