From how much euro do you get a satisfactory piece? It should run reasonably smoothly and should not take three minutes to show up on the desktop.
Is a tablet also suitable for you? If you just want to watch Netflix, it's a better choice.
300 euro definitely take a laptop with 1080p
Would recommend it, but use a 2x memory module at the same time, otherwise you will give away performance. If you don't do much and pay close attention to the device, the thing will run for an eternity.
I would spend about 500 euro.
It is important that the laptop in your case:
An SSD with at least 240GB has
A Full HD (1080p) panel has
The best IPS panel
Minimum CPU with native 4 cores (Ryzen 5 or i5 newer generation)
Minimum 8GB RAM
Basic little tips:
Inexpensive laptops often have CPUs that are absolutely electronic waste. Therefore, rather invest a little more! And make sure that the laptop does not have an HDD but an SSD. An HDD is completely superfluous for your application.

You don't need more, it will also be enough for other things
