You should look at the organization / methodology of the survey, but generally it's a positive to get ranked IMO. I used to get surveys these yearly at a past job from the Boston Globe / Best Places to Work and it was basically a third-party email to all employees with a survey you'd fill out.
The most anyone could realistically ask you to do was please fill out the survey positively to try and support the company if you believe it's a best place to work and remind more people to complete the surveys. I don't think companies are really out here trying to game the more reputable surveys, and it would be pretty easily for single employees to defect/report if they were. They also required some level of basic written comments from employees.
Probably a mild green flag for quality of life / general happiness from current employees for the past year.
