Ask HN: Choosing the right returnship?

I haven't worked a full-time web dev job since 2014, and from 2015-19 was doing freelance work with technology mostly stuck in 2014. I am aware of how much the web dev game has changed since then, but have lacked the will to catch up with the tech on unemployed time. The drive and curiosity that led me to learn web dev in my early 20s isn't there anymore.

I found out about returnships and they appear to be aimed towards people like me, getting back into the workforce after a long term leave.

However, information on returnship experiences is sparse and can't find a good guide on how to pick one that is a good fit to restart my career. I'm guessing that returnships are niche because of the circumstances one must be in to join one. How do I weigh the pros and cons of a company's returnship program and make sure I am going to get the proper experience and training and not be up the creek without a paddle?
