As I look at your list of question, the questions are mostly good and valid, but all seem to be focused on you.
Try to come up with some questions about the environment, the culture, the interviewers that don't just relate to you or you doing better. I'd avoid anything that is definitive immediate feedback/advice, because that's kind of like asking them for a decision, right away.
"Based on what you’ve gathered about me, what should I improve on to better fit this role?" - would be excluded, if it was, well, me. You're asking them to focus on where you fall short. They'll look that over, and evaluate it, but you don't need to make that more prominent in their minds.
Asking about training is good and appropriate. Clarification is polite and helpful, yes. Anything else they feel you should know? Also good.
Perhaps "what do you like the most about working here?" Or "how long have you been with the company, and did you have other positions here before your current one?"
or maybe a question about what the future potential would be for someone hired for this position who excelled at their job.
Those are generally positive questions, and they communicate an interest in the company, the people there, and the work environment, beyond just getting a job and getting paid.
