So bizarrely the best experience is to self host and pirate. That’s what you get when the entire entertainment industry is hostile to consumers.
When Netflix first became big, it was popular because it was a one-stop shop for almost all your content. It was like a big library of content in one place, you pay a reasonable monthly fee and it’s all there. Piracy dipped as a result.
Now all the content is fragmented into numerous walled gardens you have to pay separate fees to access. People can only consume the same amount but now they have to pay 4 or 5 fees as the content is spread out.
Unsurprisingly piracy is booming again.

Yes you can do loads with your Raspberry Pi. Certainly you can install ARM based linux distros onto it, but with an older model you’re best using a Pi specific linux distro.
The official Raspberry Pi OS is linux and is compatible with all Raspberry Pi models - there is a universal 32bit version and a 64bit version for newer models 3+.
There is also Dietpi which tries to be more lightweight and optimised.
You can image either distro onto an SD card and run it on the Pi. If you connect the pi to your network you can run it headless and access it via SSH on your PC.
However, if you main aim is to learn and play with Linux, then it is worth considering alternatives. For example, you could install VirtualBox on your Windows PC, and create a virtual PC to run any X86 linux distro you’d like on it. That can include small systems with command line only or a full desktop environment of your choice. That would likely give you much higher performance and options than a 10 year old raspberry pi can offer.
The Pi is good if you want an always on server device to play with Linux on. The Virtual machine route is good if you want a more powerful system to play with occasionally when you feel like it.
