Although React will make you more employable, Vue is the easiest first framework to pick up aside from svelte. When you're just getting started, it's important that you make progress to stay motivated so yes I highly recommend Vue. I use Vue at work every day so it's not like there aren't Vue jobs.
Node + ExpressI love node because you can use the same language in the front end and the back end. Express is the gold standard for APIs and it's my favorite server side framework to use by far.
PostgresPostgres is definitely the most popular relational database in the web dev space at the moment. I slightly prefer MySQL just because I'm more comfortable with the edge cases but postgres is the better skill to have. Either way, you'll need to learn some SQL. Arguably you can avoid SQL if you use an ORM but I think it's a good idea to learn SQL regardless.
OverallGood choice in tech. Learning Vue first helped me to learn React later on. It sounds like you're trying to learn too much at once. First I'd focus on JavaScript, html, and CSS. Then I'd learn Vue. From there you can learn react if you like the front-end or node and express if you want to get into backend.
You might also benefit from learning Firebase/firestore over SQL because it's a bit easier and has a little bit less setup.
Also look into supabase for postgres. It's my favorite place to host postgres databases and you can get started for free.
