Having upgraded the lighting on both my F-250 and E-350 over the last few years I can chime in here with what I have learned and done. A lot of your lighting is dictated by your bumper. Some have holes or slots, others have a baja bar to clamp to or a big flat top to mount on. All of these can limit the size light bar you may choose or placement of fog style lights.
I love light bars in addition to other lighting up front. I wire all mine to come on when I engage the high beams, on my van I could roast a chicken in front of all my lights!
So, first off, make sure when you engage the high beams that the low beams do not turn off. Sounds silly I know but this is more common than you think. You can typically tell this happens by when you engage the high beams momentarily you get both but when you just turn on the high beam switch you get just high beams. If so, get a BriteBox to solve this first.
Now, as I said, I have done a few lighting upgrades. I typically wind up with a mix of brands as one bumper only uses a certain brand or type and light bar can be something different. I really like my Rigid 20" light bar. I would have gone bigger but to mount it under the Baja Bar on the bumper I was limited to this size. Now you can get a variety of lighting options within said light bar. I chose the driving lights/spot combo. I would HIGHLY suggest you go to Rigid's special web site where you can select the different lighting options you are interested in and then see the light output online in a demo they have where they put all their different lights on a vehicle and let you see the output pattern. It will really help you figure out what you want to run.
I hope this helps a little. On my F-250 I changed out the factory fog lights for Rigid Driving Lights, added a flood/spot combo light bar and installed a BriteBox. On the E-350 I did a combo driving/spot light bar and have 4 spot lights mounted in the bumper and again added the BriteBox. The van has a massive amount of light out front, the pickup has plenty but the Van/chicken cooker is most impressive!
I will also say that the vast majority of my off-road/backroad night driving is in the deserts. Snow or constant heavy rain would quite likely require a different setup most likely. Also, if following others off-road, their dust is essentially like fog and once again a lot of light is actually worse as it all reflects back at you. But for long adventures in the CA/NV/AZ/UT deserts I find a lot of light to be perfect.
