Classical music newbie needs your suggestions

I purchased around 300 like new classical albums last summer. Music from a wide range of composers. I also purchased around the same amount of operas. (I may sell those).

I’m finally retired and able to pursue a lifelong desire to understand and enjoy classical music.

Pieces that move you to tears, or pluck heart strings. Your all time favorites.
The albums you’d take to that desert island.
Any suggestions are welcome.
