In order to get the best viewing experience, you would want the following specifications on your TV:

At least Full HD in quality (1920 x 1080 pixels), any more than this is great, but any less could make the screen blurry.
The TV should also be a 'Smart TV'. This will enable it to connect to various online streaming services like Netflix and Disney Plus.
It should also have a High Dynamic Range (HDR). This will show you more colours and increase contrast.

Don't worry about the size of the TV, purchase what fits in your space. All TVs also have a high enough refresh rate that this specification can also be ignored. Similarly, your TV's viewing angle is also largely irrelevant.
