A couple of thoughts.
First, if this is your first fence ever, I'd opt for really simple. Get something going to learn what you like and don't like. Too many times in my WW "career" I've thought something was a great idea but when I used it found out otherwise.
That AL angle looks like a good idea but I wonder how you are going to make a DC port in it and keep the two sides aligned. The split fence may work against that. Maybe some 1/2" BB on the horizontal part of the AL piece would help.
T Slots are nice in the fence face. I made some stop blocks with cam locks that fit in my fence's t tracks and they work really great - fast set up and tear down.
Unless you already have T tracks in your router table, I wouldn't bother at first. Just use clamps to hold down the fence. See how it goes for a while and then add after you get a little more experience with the fence.
I guess my advice could be summed up as "go slow, don't do unnecessary stuff".
Measure twice, cut once and CROSS OUT THE WRONG MARKS.
