First of all, I'm sorry to hear about your difficult circumstances during your MC vac scheme, that can't have been easy at all.
As others have said, I think you really need to focus on yourself and truly figure out where you might be going wrong. You clearly have a great CV and lots of strengths but quite frankly, looking good in paper is not enough. It's about how you 'sell' your story, your motivations and why you are right for the job.
Being completely honest, your post comes across as though you expect to get interviews because of your CV. This might be stopping you from actually putting in an holistically strong application. I wouldn't leave anything to chance - make sure you are demonstrating depth of research and genuine motivation for the career & each firm you are applying to. As others have said, I also wouldn't rely too heavily on other people's opinions of your applications - they are not recruiting and they don't really know what recruiters are looking for. I would also avoid comparing yourself to others - how do you know that others people's applications are objectively worse than yours in the eyes of the recruiter? Grades are no longer the most relevant factor in a lot of cases with some firms ditching minimum requirements.
Veering towards the idea that inclusive practices are somehow contributing towards your lack of success is also dangerous - your focus should be on how to make your applications stand out that little bit more than they already do so that you're able to progress.
