Need help choosing my second ship.

Hello, I am a new CMDR in my second day of service.

I have recently purchased a type 6 transporter which has been doing me well in my recent endeavors, Doing A <–> B trading.

I would like to upgrade to something more suitable for the job. I am looking for something to further help my profits before I get into combat, so I do not intend on purchasing something for combat ability.

I would like to hear any recommendations you all may have. I have been trading for money, but also enjoy exploration as a secondary hobby, and do feel like I am neglecting missions.

If I had to give ignorant priorities as a new CMDR, I would say I heavily lean towards cargo capacity and jump distance right now. I do not greatly understand modules, have never done horizons content such as upgrading either, so advice with the recommendation would be greatly appreciated.

Edit due to stupidity: Originally I stated a budget of 5 million credits, but I meant 50 million.

I hope this was informative enough, and if not, please let me know and I shall answer any replies and edit this accordingly.

Thank you.
