Awning Type or Method

I'm doing a cargo trailer conversion. 7x18' flat front cargo. Its completely a living cargo trailer, no toy hauler or equipment.
I'm looking to do an awning, and I'm stuck on what's the best option. I will have a brand new aluminum cargo trailer in about a month.
So options I'm considering, and I'd love thoughts on best option, and best brand for price within that option
1. Box Awning (like the thule awnings)
2. Bag Awning
3. Standard awning with legs etc.
4. DIY Awning (ie tarp or something like that)
I'll do install myself. I don't feel attached to motorized, but would consider it, but I expect it to be not worth the money to me.
