There's no right answer for what to say on a date. A good connection with someone is when you both find a good pace of vulnerability and validation.
You don't want to be over vulnerable, asking too much validation, over whelming them. But you also don't want to be cold and distant, giving them no reason to trust you of let them see you're starting to trust them.
Asking for thoughts on an issue can be a great way to do that. You do something mildly vulnerable, talking about an issue in your life that isn't too over the top, hopefully they validate that, and they'll be vulnerable in expressing a thought on the issue. Validating doesn't need to be agreeing either, don't feel forced to agree. Validating is just treating something as rational, you can see how they might think that, you remain open to it's possibility, but you also might currently think it's wrong or right.
Just be honest, forgive your mistakes, if she seems overwhelmed dial it back, but generally try to assume she's operating in good faith. Don't assume the worse. You'll be fine.
Advice can be a fine thing to try, just don't over do it. Be honest in interpreting her answer. A phony "I should do that" will seem cold and untrusting.
