The trouble with Classical music (as you have already found out) is that is covers such a wide range of periods and styles, requires a variety of performers (orchestras, solo instruments, singers, choirs, etc) and was written over many hundreds of years. You really need to sample lots of pieces before you can decide what style of classical music you enjoy. Personally, I don't enjoy much Early Music, Renaissance, or Baroque, but others love this stuff. I listen mainly to music written since Beethoven's time, so what is known as the Classical, Romantic and Modern periods - music mostly written since about 1800.
Your best bet is to tune into a classical music radio station and listen to their varied offerings and you'll soon find what you like and what you don’t. I suggest Classic FM, a UK-based radio station that's available worldwide via internet services such as TuneIn that most streamer should be able to provide. This station plays constant, relatively "light" and popular classical music and each piece is introduced (without too much babble), but there are adverts to annoy you! Your streamer’s screen or control app should show you what’s playing at any time, so you can make notes of pieces you enjoy.
Other more serious stations such as BBC3 also play plenty of music but there are also long and often heavydiscussions on music or composer subjects - and much of that is rather too obscure for newcomers to classical music.
Good luck – there’s lots of truly great music out there to enjoy.
