So am I the minority wearing pants and long sleeve shirt? Will I get much faster with the usual cycling clothes?

are you a cyclist or do you ride a bike? Is it a race?

I have been a transportation rider for some years now. Owing to my circumstances, I find it more comfortable to kit up rather than wear street clothes. I don't go any faster, nor do I care to. Bigger concern is that I make the coffee shop on the way in,if possible.
there are days I am a cyclist, kitted up and wanting to rack up miles, work up a sweat,etc.
usually, i am a commuter. I don't have a shower at my work. My dress code is semi professional, so i keep deodorant, wipes, hair goo etc at work.
I switch between a bike with panniers and a bike where I only carry a backpack, depending on cargo needs. I do keep an extra change at work just in case.
If I really feel the need to pour it on, i do it on my way home, cause Im gonna shower when i get home, anyways.
keep at it, you will figure out what works best for you. as much as I want to ask is what do you want your commute to be? I have decided it is my chill time more than anything. and riding full on in a city setting is not always advisable.
