It’s been a couple of years. But even the oldest iPad - the one from 2010 - was able to download the “last compatible version” and stream Netflix.
Even an older iPad can run Netflix and Plex and maybe a couple of other streaming apps. You should be able to use it for Spotify and definitely Apple Music.
Maybe not the oldest version any more: https://x.com/fcbunn/status/1565036107049336832
