Up-skilling as a Product Manager

Hello All!! Needed some advice with upskilling to further my career in Product Management and add more dimensions to it.

For some context, I have 4.5+ YoE in the software industry, primarily functional roles including about 3 years in Product Management.

I want to up-skill myself in some hard skills as I think I have decent exposure in soft skills/functional aspects of PM but lack in the former.

Have been thinking of the following:

1. APIs (Conceptual and hands on)
2. Data Analysis (SQL to be precise)
3. Low/No Code Tools

I have about 6 months before I start looking for a new role and want to add these to my profile so as to land a good job.

Please share your inputs and feedback if these would be useful in a real-life scenario and any other suggestions, if applicable.

Counting on the advice and thanks in advance :)
