Some of them to Cloudflare Streaming as per my recommendation. Their dashboard is easy enough to use for your typical digital marketer and it spits out an embed script that's as easy to integrate as the Youtube one. They also don't have much traffic, so they barely get above the 5$ minimum charge.

1 or 2 ended up with Vidyard (or a similar for-marketers solution I don't remember the name of). For the rest I don't know what they ended up with.
