If you can pay for it, go for PhpStorm. You won't regret. It may not be/seem as simple as you want, but I think it is just a matter of practice.
A free alternative would be Visual Studio Code. I don't know the kind of Javascript support you need though. If you need only simple JS editing, PhpStorm is the way to go. If you need some JS debugging, you might consider PhpStorm and VS Code. If you need some advanced JS usage, you may want to consider PhpStorm and WebStorm.
If you are using only Vue.js, you could consider Amazon S3 for the static portion of your site and Amazon Lambda for the bits you need to store data (also in S3).

This setup would require more work on your side, but it can be WAY cheaper than EC2 instances: it can be from $0 to $3/month. If you use only AWS free tier, you can make a very nice app paying for nothing for the first year, at least.
If you want to develop an internal only tool, go for something that delivers almost everything out-of-the box.
Drupal delivers a lot. It has the basic features you need and with the help of some extensions you can have the others. You will need some configuration, sure, but the programming work should be close to none.
Django is an awesome framework and already delivers a lot of work done (thanks, django-admin), but you still need to code a lot to get your feature set to work.
