evalda I would personally say no, workspace isn't aimed at individuals or families at all.
I use WS as my threat model is just security, I could use a standard Gmail with advanced protection and likely have better results.
The issue with WS is it's designed for business, it has a lot of limitations that a normal user would want, want to share a sub outside of WS? Won't work, for example, Google home is also restricted.
If you can, stick with Gmail and setup a family plan, if you need more security just enable advanced protection with Yubikeys or Titan keys.
One thing I haven't figured out yet when testing a Gmail is how to get my pixel to act as a security key, it works simply on workspace, not on Gmail.
