An anecdote for you, FWIW...
Today I uploaded 100 new pages to one of my sites, each page a variation on the same widget.
I submitted a sitemap to Bing Webmaster Tools, containing the 100 new pages.
Bing crawled the 100 pages immediately.
One hour later I got my first organic SERP click for one of those pages, via Bing search results.
One and a half hours later I got an organic SERP click for one of those pages, via Qwant search results.
