Instead of a bumper might look into a "light bar" that will bolt to the OEM bumper and easily allow more lights.
I NEVER install fog lights. They are always "Auxiliary lights" though they very likely are a fog type of lens/reflector. The reason is that fog lights are only legal in KA to be on with low beams and I typically use them to "fill-in" the near stuff when the highs are on. "Driving lights" are only legal with the high's on, so I never install those either. Its all semantics, but it may become important if a LEO asks about your auxiliary lighting.
A trick that I saw used on a serious pre-runner with a lot of lighting was a master switch. It powered up the control circuits for the all of the light relays. Turning it off, like for on-coming traffic or lights in a trucker's mirrors, killed all of the secondary lights. Could turn it on, select the lights desired, and when needed turn them all off and back on with one switch.
I'm not a fan of LED lighting because the blue tint of the light looks "hollow" to me. Almost like its light, but not really LIGHT. Can't explain it any other way.
I have a set of HID's and a set of lights that were incandescent that are almost converted to HID. The difference between 100W incandescent and 35W HID in the same lens/reflector is impressive! Been thinking on where to mount the HID's on the camper. Up on the leading edge of the cab-over would be the most effective, but the mounting options there are limited or become a complicated fabrication for something we'll likely rarely use.
As to brands of lights, I've used Bosch, Hella, some ancient Dick Cepek's, and old school landing light bulb KC's. A friend has two sets of PIAA's that he really likes. I look to see what is used in off road racing or rally racing, both of which I see as a decent barometer of good lights vs. not good. Baja Designs has been used extensively in off road racing on both 2 and 4 wheels. As have Hella and KC. Rigid Industries has a good name, but I've no experience with them. Warn's lights are supposedly made by IPF, which has a decent name in lights (though mostly unknown in the Sates), but those that I saw were not impressive at all.
Some of Dan's "white pages" are OK, others I disagree with most or all of his points. I'll never buy anything from him as I got a serious run-around the one time that I did try to buy from him. I wanted a light that he carried, I wasn't going to justify what I was using them for to him.
Where a receiver mount winch gets iffy on strength is when pulling sideways. Trailer hitches aren't designed for that high of a torsional loading as a trailer just can't generate it. This is why most cradles have a max winch capacity limit. Getting battery power to the winch is not difficult, but does involve large cables and connectors. That expense multiplies if you want to run it at the rear.
