I guess my issue is one of my main focuses is speed! I ride a road bike and love riding quickly. Maybe I'm just stuck with a backpack

Maybe your bag was too big. You could always look to ride as fast as you can between home and work accepting the limitations of hauling stuff and then really give it some beans at the weekend. Otherwise, as you say, you've got to carry the stuff one way or another.
When you mention the gym is that somewhere you could leave stuff in a locker? If so you can cycle to work on a Monday with a week's worth of clean clothes and put them in the locker. Then you cycle in, shower, change, whatever you need and at the end of the day you change back into your cycling gear and ride home. On a Friday you take a week's worth of dirty laundry home with you, wash it, then repeat the following week.
