Personally, I'd guess Jurassic World finishes first out of all that and maybe Lightyear second, given how crazy people are for Toy Story after all these years. I love Dr. Strange, and he was a major player in NWH and Infinity War, but it is going to be a movie that you need several levels of Marvel depth to fully understand, I would think.
Then again, I use my wife's interest in movies as a barometer. She loved No Way Home, she did not like The Batman after the first hour or so. She will absolutely go see Top Gun on opening night because she loves Tom Cruise. She won't be interested in JW3 or Dr.Strange. That's the niche that Top Gun is going to pile up the #s on - women and couples where the wife isn't interested in Marvel or dinosaurs.
