There wouldn’t be any “h” if you thought of it in terms of Spanish sounds.
If you really get into the weeds, the funky spelling can sometimes give you a clue about how the word is pronounced. (But only sometimes.) For example, “rhetoric” can have a bit of an “h” sound, especially in British English. I notice it some in American English too, but it can vary from person to person.
Or “gnats.” The “n” is a tiny bit different than if you said “Nats,” like the baseball team. You obviously don’t say the “g,” but the tongue comes up a little in the back of your mouth, almost like you were going to say a “g.”
That’s nothing to worry about, it’s just something I’ve noticed.
One you’ve heard a lot of times. Otherwise, you just have to try different ones and see what you like. I like Mozart (Marriage of Figaro, Magic Flute). The music is pretty and it’s a little more laid-back than some of the dramatic Italian operas (Turandot), German ones (Wagner), and it doesn’t sound like a party (Carmen).
Tosca is one of my favorites, and Fidelio too. You can always find arias or clips on Youtube to get an idea if you might like something.
You might try lieder (classical songs) too. They tend to be more soothing. It’s usually just a singer and a piano, no big orchestra. I like Schubert, something like Die Schöne Müllerin (the Fair Maid of the Mill), or Brahms.
