Not sure I fully understand your question your question, so I'll rephrase it to ‘what is the best way to get better at structuring?’
I'd focus on these 3 things.
1. Learn to do it from first principles
This is a key skill that almost guarantees that you're going to be among the top candidates they are interviewing.
Most people learn frameworks by heart, which is why their performance is, at best, average.
If you get to the point where you can structure any case regardless of context, you're where most first-year consultant are.
I actually recently launched a workshop on this: Masterclass: First Principle Structuring
2. Expose yourself to different structuring patterns
The more cases you attempt to structure, the better you'll get at doing it.
So practice does matter in that sense and collecting enough examples so you develop your lateral thinking on the topic.

3. Get feedback
This is how you ensure you constantly get better.
Even once you're in consulting, you get feedback on how you structure problems from people with more experience than you.
So at this point try to get feedback from either experts or people who are already in consulting for a while.
Best,
Cristian
