Create a simpler version of Angular with essential features

I am creating a pet project for my family to manage all of our contracts. Basically everyone of us cancels their contracts once a year and lucks for better conditions. So we need to track them with due dates, conditions, partners, etc. Some of us like my father manages contracts for over 100 people Now professionally I work with Java/Spring and Angular or PHP/Symfony and I think it often is a mess to support and update those. What stack should I chose to support and update this project for at least the next decade if I don't want to deal with breaking changes and vulnerabilities in dependencies all the time? I am willing to use any language or framework if there is a clear reason why that would benefit my project. I think for the backend it shouldn't matter that much, I could probably do it in plain PHP, but being burned by JS from the early days from even before even EcmaScript5 I have severe PTSD just thinking about it. For a short moment I even considered going back to jQuery. I wish there was a dumbed down version of Angular (MVC, Standalone Components, Scoped CSS, Automatic change detection like zone.js did before signals). Basically feature complete without caring for performance not needing any updates in the coming years aside from changes in browser api and security. Or maybe there is and I didn't find it yet?
