Convert making an effort to recite the Quraan in Arabic

Q: I am a Muslim convert. I converted to Islam 1 and half months ago Alhamdullilah.

I have a question about reading the Quran. I want to make it my habit. I would like to do it in a way that is the most beneficial for me. I don't know Arabic, I read an English translation by Dr. Mustafa Khattab, so reading random surahs (as my friend recommended to me) doesn't work for me because I can't remember its content. It would be better for me to read it by topics, so I can focus on one topic at at a time and do notes, remember more.

Is there any particular order of topics I should follow? If not official, maybe then your personal? I'd like to go from things that are general, to laws and details etc. In my Quran there is an Index that I could use to look for exact ayas.
