Hear it in context
Notice where the phrase sounds natural.
The main topic of today's meeting is how to improve customer service.
In my opinion, the main topic of the article is the importance of teamwork in achieving success.
Fix the pattern
One small grammar move makes it sound right.
Not: The main topic of the meeting was about the budget.
Say: The main topic of the meeting was the budget.
Don't add 'about' after 'was' — 'the topic was the budget'.
Which sounds natural?
Tap the one a native speaker would say.
'Main topic' is plain and natural; 'central theme of our discourse' is academic.
Build natural chunks
Words that usually travel with it.
