I carry a camera with me just about all the time. It is a significant commitment. You need to consider what kind of bag you can carry all the places you will go and, if needed, how you will secure the camera.
The simplest solution is to depend on your phone camera as the one you always have, but clearly you want to carry a serious camera. I'm not clear on what precisely you want the bag to fit, which would help a lot in offering advice .
For a convenient "everyday bag," I prefer a bag which holds just the camera with one lens, a spare battery and a little extra space in case I want to fit in my phone or other small item. If the bag is any bigger than it has to be, it isn't serving me as conveniently.
My camera is a Fuji Xpro 1 or 2 and I own mostly primes, so even the fastest ones are small. The Crumpler Four Million Dollar home will easily accommodate this and can fit a second lens, depending on which pair I take. Very good protection, opens quietly, hangs well, doesn't look stupid. But this won't work for you unless you have similar sized gear .
The Billingham Hadley Pro will hold a shocking amount of gear relative to its size, holds it close to the body, looks good with almost any dress level (shorts, casual, suit and tie), operates quietly and rides close to the body. Protects gear well, handles rain. Lasts much longer than most still looking good. Not inexpensive. I can carry two cameras with lenses attached, strobe, batteries, three other lenses, ipad and I haven't even put anything in the front pouches yet. I'm fairly confident it will carry as much gear as you would want to have in a shoulder bag (unless you are Arnold Schwarzenegger)
A backpack is always a better way to distribute a large load, especially over time.
A belt system has good distribution of weight like a backpack and quick access to gear, but looks odd . If I am "working" this is a good way to go, but you have to be willing to be like...I don't know... Batman? (or a paratrooper?). Think Tank's belt system is what I have.
Which leads to the social aspect of carrying gear. If you really want to carry it every day, you need to think about what is not going to be awkward in your environment. Is it odd to have a shoulder bag in your workplace? Does the bag get in the way of work tasks? Etc.
