There's no reason you can't get short , intense bursts of exercise on your commute especially if there are hills in the way or you time yourself and try to get it down. Years ago I used to do a 40 mile round trip to work by bike with a few good hills on route , so there was a mixture of hard anaerobic effort and lower intensity pedalling. After about 3 months of that I was probably never thinner and fitter. Regards sweat, this depends on if you can shower at work I guess and also how sweaty you get. If you wear cycling clothing that can absorb a lot of the sweat and then change and spray some deodorant when you get to work you really don't smell all that bad.
