First time flying Business Class - and have some questions with probably obvious answers…

Hi all, I’m travelling from my city to Doha (7 hours) then to Sydney (14 hours), and then back - both legs on Business Class, and it’s my first time flying Business. So I have a few questions about it, and they definitely have obvious answers, but for piece of mind, I wanted to just know for when I get on board:

1. I had seen you can dine anytime - so do I just tell them like two hours into the flight, or a specific time? How does that work?

2. I’m assuming I can ask for a drink anytime and it’s all part of the price? (Yes I‘ve just asked that question, but wanted to know every detail!)

3. I’m flying on B787 and A380 - which seats are best to choose, and I want to choose a window seat.

4. Am I correct in saying flying Business Class allows you access to lounges in my city, Doha and Sydney, as well as fast track security? Are there any other on-the-ground perks?

5. Is Wi-Fi included? StarLink might be on A380 by then, but in case it isn’t, is it free for Business Class passengers?

6. For getting a flight attendant to make the bed for me, do I tell them a specific time when I want it made, or do I just use the call bell and ask for it to be made?

That’s pretty much all the questions I have! Thanks to all that reply!
