Things to do for final exit visa

Dear Expats,
I have been laid off from my company my Iqama is valid till May 2021, I have been given an option to get a local transfer or move back to my home country on final exit. I have decided to go back as there are not enough opportunities in KSA.
I have one bank account and a zain sim. I do not have any housing contract or vehicle on my name as I was new to Saudi came here in January so due to pandemic I shared my friends apartment.

Now I have a few questions:
Shall I first close my bank account and sim card before asking my company to provide me a final exit or the final exit can be issued without closing these two and before I am about to fly back I can do these obligations ?

Anything else that I have to do please mention. How much time is taken usually to get a final exit visa ?
P.S there are only special flights taking people back to my country and I am not sure how much time will it take for the company to get a ticket for me as there are limited number of flights.

Many Thanks
Any help in this will help me a lot!
