It's based on the type of site you reserve (Full, Preferred, Premium, Tent). The system will "pre-assign" you a site based on the level you reserved factoring what was vacant the night before or who is leaving that morning. You don't get to pick a site. Everybody gets a pre-assignment. With that, you can still go in and ask about a favorite site or two if you have faves but it solely depends on if it will be vacant and available for assignment.
As for meals, we don't come back even from MK (most convenient park to FW) because of the travel time coming and going even if we drive to the parks and skip the bus system (our preference) which to my Type A personality feels like it takes forever. However, you certainly can and people do come back sometimes to rest or nap mid-day (or check on the pet) and then head back to the park. So it does happen. We do take the boats to MK or Contemp (and walk to MK). Few people in the campers/tents/rvs do the meal plan since it requires every day of your stay to be on the plan.
We packed a picnic lunch into the parks when we had the 3 kids (and two adults) and then bought a counter service meal but as we only have one "kid" 20yo now at home, we eat more table service (because I can).
When in October 2020 are you planning to go? We on the Camping Board have discussed a group of us all camping together at the Fort in October 2020 during the week of the Columbus Day holiday. If you plan to attempt to be at the Fort during Halloween (which is fabulous), it fills up more than a year in advance. So book H early if that's the plan.
Come back at us with more questions.
