I would definitely recommend you to go with Spring Boot + AngularJS + jQuery. Reasons: 1- You have an experience of 4 years with the above-mentioned stack. 2- As you mentioned that you wish to work as a freelancer, your stack is the perfect one for finding good bids with a little less effort than that of PHP + Laravel + Vue.js.
i highly recommend picking anything BUT angularjs. this framework is dead, and no longer active.
same goes for jQuery. this should only be maintained on legacy projects.
What about Angular ? (https://angular.io/) Doesn't seem dead to me...
