Redirections help?

My blog currently has 526 live posts, and 245 redirects – using the “redirection” plugin.

52 of those redirects are deleted posts to alternative posts, tags to categories, categories to tags, and one redirecting AMP to non AMP after uninstalling an AMP plugin.

The remainder are all redirecting the post format /yyyy/mm/pos-title.html to https://www.myblog.com/post-title/ – and around 10 redirecting /yyyy/mm/pos-title.html?m=1 (old blogspot mobile format) to https://www.myblog.com/post-title/

I started my blog Blogger/Blogspot with my own domain http://www.myblog.com/ and post format /yyyy/mm/pos-title.html

I migrated from Blogger to WordPress.org in 2013, using the existing /yyyy/mm/pos-title.html format, then sometime later, using the WordPress permalinks settings I changed the format to “Postname” https://www.myblog.com/sample-post/

My blog is currently hosted on Siteground GoGeek, using the free Siteground SSL, and I also use Sucuri Firewall.

Over the years I think the changes I made have sometimes been in haste, without having much idea what I’m doing, and so now I have maybe far too many unnecessary and incorrect redirections. Some of which might be redirecting 3 or 4 times.

What I really want to know is, is there a better-more SEO and user-friendly way of handling these redirections?
