I do a little bit of everything, and it will depend on the intersection.

If there are 1 or 2 cars waiting for the signal, I'll just "take the lane", and pull in behind those cars, or sometimes pull in behind, staying at the right rear quarter panel of the cars.

If there are a dozen cars, I'll often pass them to the front of the line

However, it also depends on the intersection.

Knowing the order of the light sequence is important. Will the turn lane or the straight lane get the first green?

If my left turn leads into a right bike path, then I'll proceed straight through the intersection, aiming at the line of straight through cars on the opposite direction, then take a sharp left. This allows cars to cut around the corner and pass me if they wish. Lining up on the right side of the turn lane helps with this approach (and sometimes I'll pass cars to get a good starting position).

On the other hand, if my left turn leads to a median strip bike path, then I'll just pull in behind the last car, on the left side of the turn lane. Once the oncoming traffic clears (and no oncoming turning traffic is possible), then on green, I cut into the oncoming traffic lane and head towards the bike lane. That allows the cars familiar with the intersection to pass on the right, and my intentions become clear to everyone.

I've got one light that often turns to a blinking yellow. I just take my place in line. When traffic clears, I go.

My biggest issue is when I pull into a turn lane, and am unable to trip the signal. I'll often go once the traffic gets very clear. But, then there are those cars that choose to stop 50 feet behind me, and nobody trips the signal. I have to wave them forward to get onto the switch
