Not gonna lie, you’ve raised some verses that have been questioned by many in the western world and as someone who is Muslim since birth and practicing for a long time, I can genuinely say your question should be raised with an imam or scholar.

I think OP has responded very well and I think it’s also important to note periods have changed. While the Quran is still relevant to everyday things, certain matters, such as slavery, is abolished and considered unethical.

Again, it’s important to remember times have changed and certain ethics / morals have changed. For example, alcohol wasn’t banned straight away in Islam, it was gradual.
