Advice on how to choose between two jobs

I currently have a job offer for 110k(a)and another for 100k(b). A is a small sass company with other startups that are subsidiaries. B is a mortage company. B has better benefits, but A has more potential for me to work on different products. A would probably be more work while B would be a cozier job, but not as interesting. I’m not sure which way I should swing towards and any opinions would be helpful.

Edit: company B is actually a housing financial authority
