I'm curious to hear other people's takes on this, too. How unique is the content on each page? What do the crawled and not indexed vs discovered not crawled ratios look like relative to indexed pages? What does linking to the detail pages look like (category pages, similar items)? How much authority do category pages have in terms of backlinks? Page speed issues-- in GSC, can you manage average download time <100ms (makes a huge difference)? Noindexing may help-- if you just initially handle that based on page content uniqueness and/or presumed MSV potential for the page. Otherwise, based on your language, can you request a quota increase from the 200/day notifications for the Indexing API? If you like reading about the topic, maybe head to BHW forums (very poor SNR, though) and read about what some of the more unscrupulous people are doing to index MM+ pages/mo and extract some of the less-risky strategies (e.g. don't abuse the news/job posting APIs to get spam content indexed). As additional commentary, the last 2-3 months have been chaos in terms of algo updates. There was essentially a 30 day period where Googlebot all but disappeared for most sites, then the two HCUs and other random updates tossed in for good measure, stacked with desktop infinite scroll and the switch to mobile first indexing. I can't remember as many changes happening in a single quarter in over 15 years of being SEO or SEO adjacent.
