Job offer from two schools

Hi everyone! I currently have two schools offering me instructor positions and am struggling to figure out which is the better option. I also would love any insight into other factors that I should be prioritizing when picking an employer. Any info helps!

I've done my interviews at both schools now and really enjoyed the people and their passion for the work, so there's no overall leader in that category. However, I only got to see actual lessons taking place at one of them during my interview (school 2).

Here are my summarized options:

School 1- $15-17/hr, paid training, includes lifeguard certification, shorter commute

School 2- $20-25/hr, paid training, no lifeguard certification

I only included the lifeguard portion because I felt it would be advantageous to have, plus school 1 offers lifeguard shifts to pick up so there would be more opportunities for extra hours within that school and their other nearby location. If this is not something I should even worry about right now then please let me know haha.

Thank y'all again for your help!
