I think Patrik and Alex are right: if you're comfortable with Spring Boot already, you'll be more productive right from the start.
If you wish to learn something else besides, both Laravel and Express are good choices. They aren't in the same category of frameworks: Laravel is an all-in-one solution, while Express is more like "build your own stack from different parts". Which implies that you can use whatever you want as a database engine: MySQL or PostgreSQL are perfectly valid choices (in my school, we teach Express with MySQL, because SQL is still a big thing here in France, and a sought-after skill). You can use Sequelize or TypeORM which support all major SQL DBMS.
Express is widely used, but if you're seeking the JavaScript equivalent of Spring Boot or Laravel, you probably want to look at NestJS. The only potential downside is that it's still young, maintained by a small commmunity, compared to those behind Spring Boot and Laravel.
Bottom line: using a stack tech, that you enjoy and are comfortable with, matters. Spring Boot + Vue.js seem perfectly fine to me. But do forget jQuery if you're using Vue.js, React or Angular, because it will definitely bring more harm than good!
Thank you for sharing about the Javascript ecosystem. I have tried some JS solutions like Nuxt and Strapi headless CMS that I found could be interesting for small website development (Jamstack as an alternative to wordpress). Those are developed by French teams I believe ! I will look into NestJs. I think that’s what I’m looking for, some good and reliable tools in Javascript.
