In case you didn't know, the NFL releases game video on their website which can be downloaded as part of their basic NFL+ subscription ($7.99/mo). It's not the broadcast feed, it's the "all-22" views where you can see all the players on the field from above and each end zone. This is the same footage you see on many game analysis videos by football YouTubers.

Now that every NFL player wears a tracking beacon between their shoulder pads, there's an unbelievable amount of automated metadata available from a variety of third-party data services. The data can include breakdowns segmented per team, unit, player, drive, down-and-distance, etc and the costs can be quite reasonable depending the depth and sophistication of analysis. There is also some data available free on ad-supported sites or on free-to-join sites, including on fantasy football and sports betting sites who use the free data to attract sign-ups.
