So if you're reading a lot and can swing the cost, Orange County Library System in Florida offers a virtual card for nonresidents (including those outside the US) for $125/yr. Then you would be able to use Libby or one of the other library apps and given their size, they'll definitely have a lot of the books you're looking for. Just may have to wait on them

Edit: just to clarify that this only works if you can afford that much upfront and read enough to justify it. It's the only library I know of that will give access without requiring a US address, unfortunately it's also one of the more expensive ones
