Welcome to the forum. In my experience, real practising, meaning benefical practise that actually makes you a better player, will never sound interesting to listen to. You should pick something simple and play it very slowly again and again, making sure to stay relaxed and fully focused. If you’re making mistakes, then slow it down even more, or break it into small sections.
Most of my practise is ‘silent’, playing the keys but not blowing. This is a great technique for really concentrating on what your hand is doing, and making sure that your fingers are moving efficiently.
This of course has the added benefit that you can practise anywhere without annoying anyone!
