In summary, the technology equivalent of my 70's Scout.
As for vehicle choice consider towing, snow/ice, 4WD trails and a platform to modify. Why immediately limit your capabilities?
I think you might be selling the 5th gen 4Runner a little short there. The 4Runner's part time 4WD is perhaps not as convenient as AWD or a full-time 4WD with a torsen center diff, but it is robust and reliable. Quite honestly, if the pavement is dry, then there is no need for 4WD anyways....my 2 cents.
As for a platform for modifications, the 4Runner is well known for that, and among the 3 options that the OP presented, it is definitely the least expensive for suspension/lift mods.
