I will provide my two cents to this post.
Your school rank, work experience, academic performance, GMAT test (mock scores) are all on your side. But applying to the extended round or next year is a bit tricky. While next application cycle for sure is going to be one of the most competitive year, I believe that the extended round will also be competitive.
While schools continue to extend their application round due to the current circumstances, they have also dropped some of the requirements to apply. No GMAT/GRE/TOEFL, no application fees, etc... This will only make the application cycle for the extended period competitive since a lot of individuals will be thinking just like you and trying to take the opportunity. But remember, all of these schools are one of the best in the world and with their name comes prestige. They will rather have low incoming class but will not lower their requirements. No GMAT/GRE means they will HIGHLY focus on high GPA/essays/recommendations/WE. MBA at a top school is a once in a life-time opportunity, so do not ruin it for yourself for speeding through the application process and submitting a bad application.
From what I have heard, re-applications are looked down upon unless there is an amazing improvement. Others can comment on this, but this is from what I have heard.
At the end, if you are able to score in the 750 range and provide amazing essays and recommendations, go for it. If not, wait till the next cycle or the year after.
Remember that we do not know when COVID-19 will end, and looking at how quickly the business schools are removing requirements, it might work it your favor if they do the same for next cycle.
Enjoy and let us know about your decision. I will be glad to hear your story.
EDIT: Please also note that most of the schools are also reaching out to their R1 & R2 applicants that were competitive but declined/Waitlisted.
