There are about four tables outside available but in my opinion, you have way more people walking past you and around you than you'd have inside the restaurant. The outside tables are right near the check in stand and people tend to linger in the area waiting to be seated. The tables inside are very spaced out with much more social distancing than outside..
We've eaten dozens and dozens of times at Disney since it reopened, we always eat inside and have had no issues at all. They are very strict and going above and beyond most other establishments.
