Your pedals look like road pedals. Personally, I wouldn't want to commute on those.
When I bought a road bike recently, they tried to talk me into road pedals, but I reminded them I was also using my road bike for commuting and put my mountain bike spd pedals on. I use the single release m540 spd pedals with low release tension, so it is super easy to click in and out. You can easily control how much tension it takes to release your shoe from the pedal by using an allen key to adjust tension. I'm not mechanically inclined, but these are easy to use and hold up really well.
Trying to track stand makes me anxious, especially around slow/stopping cars. I like to ride slowly up to lights while clipped in so I have momentum when the light changes. I try to make eye contact with drivers in difficult traffic situations to assess if they see me, if they are paying attention, if they might turn, etc. Have you tried contacting your county bike coalition for advice on the overpass situation? They may have suggestions. You could also contact the city public works department about your overpass commuting experience to see if they have suggestions or could do something to make it safer for cyclists during construction.
