Where will you be staying? It's a huge area and you can find just about anything you want for dinner there. Staying onsite gives many options that are Disney specific. You can also stay onsite and easily access offsite dining, but if you are in the parks every day of your stay, time and convenience may come into play.
Sometimes it's just going to be easier to eat at Disney, use Disney transportation versus, returning to your Disney hotel and then getting in your car for another 2-3 hour expedition for dinner.
If you are offsite anyway and are driving your car to the parks, eating somewhere enroute back to your hotel is more accessible. Or you can more easily do takeout, order ahead and pick up to take back to the room.
You will have almost any option, depending on logistics and the time you want to spend traveling to the food you want to eat.
Disney Springs has some really nice restaurants and almost everyone eventually goes there to access more Disney shopping. If you are going to plan a table service restaurant, you may want to make reservations as many are very popular. Almost all Disney restaurants are family friendly. Many of the park restaurants are very good and might be an option for you to consider.
If you are looking for casual dining such as Olive Garden, Cracker Barrell, Outback, etc, they are pretty much similar to what you would get at home, including prices.
Just one caveat from someone who always has her car at Disney - they have real and city type traffic there, so you will spend time getting places. Plan accordingly, but plan in advance where you want to eat at least 1/2 of your dinners. That will save a lot of angst and time.
