Should I delete (Crawled - currently not indexed) pages?

On my local service business website I have 72 pages indexed and 432 not indexed. https://prnt.sc/dYJLZwKgg4tR
The "Crawled - currently not indexed" pages keep slowly increasing when looking in my google search console.

It appears to be 90% of my blog posts, and even some of the blog URLs like (site.com/blog/page/4) is not indexed.

Over the years I hired someone to write me these blog posts (800 words) with stock images and used local keywords like (Top 5 Signs Your Miami Roof Needs Repairs) Basically every article mentions a city and is structured like roofingsite.com/city/blog-post.

What would you do in this situation?
Im thinking about just deleting all of these blog posts that are not indexed, and going in my XML sitemap and removing everything (categories,tags,etc) and just have it show posts & pages. Which is the only areas I have made content for this website.

if you're going to delete them make sure to 301 the URLs to something else, otherwise you'll end up with lots of 404 pages, which can tank your site.

However, I don't know why you would want to remove blog posts, indexing is slow nowadays anyway, so it might take months for those posts to get indexed (although, stock images might prevent this from happening, I've heard that google doesn't like stock images anymore, so this might be a reason for why your posts are not getting indexed)...

Anyway, I'd not delete them if the content is good and the keywords are easy, I'd rather get some social signals to them, and put those posts on reddit, quora, pinterest, and throw them into some paid indexers too. I'm sure that one, or more of these methods will index them eventually

"Crawled - currently not indexed" is 90% of the time due to thin content.

Revamp posts, rather than delete. Sounds like your in a local niche, so use that to your advantage.

As @tazarbm mentioned, standard "easy to get" content like stock photos, is seen by Google as "easy to get". Something on the page has to sparkle.

Back to local... Add real photos, videos, reviews, survey results, sponsored research, charity donations, statistical charts...

Check in GSC to see if any of these none indexed pages "were" ranking for terms, and rewrite content to optimize.

Don't rush to delete those pages just yet. Google's "Crawled - currently not indexed" often means they don't find the content valuable enough to index, not that there's a technical issue.

Here's the move: Audit those posts. Are they high-quality and providing unique value? If not, improve them. Combine short posts into comprehensive guides, update old stats, and remove any fluff.
