Try and give some consideration to what each site needs and what your teammates bring to the table at the same time. I hate selfish squads where people run mozzie, warden, oryx, cav + any other roamy type op. That’s basically an L against any team that brings hard breach and uses utility to push you. I personally learnt to play mute, jäger, bandit, kaid and other info, wall or utility denial ops just because in most cases people want to frag out and lose.

On attack, since it’s pretty much the same frag mentality I mostly play ace, therm, thatcher, osa with emps for sites with outside walls like both 2f sites in club house, border, sky, etc. But generally I find that if you play more objective based you can get value from pretty much any op if you use their abilities and don’t just walk straight towards site. That’s my 2 cents.
