Off the top of my head, my top picks for this challenge would be Nyx, Limbo, Octavia and Frost since they have good CC and objective defense, and good weapon support; “complete” frames if you will. Loki, Zephyr and Banshee would all also be good picks, although missing elements from their kit here and there.
Zephyr has been my main for a long time and would be an easy pick for this. Breeze through mobile defense with turbulence, tornado for everything else except spy. As long as you know the spy routes, operator just makes things even easier.
